StemWave is a type of acoustic shockwave therapy, also called ESWT, that uses focused acoustic pulses to trigger your body’s natural healing response in painful or overused tendons and soft tissue, with no surgery and no downtime. At Laser Clear Skin MedSpa in North Beach, sessions run about 15 minutes total, most patients complete a series of 6 to 10 sessions scheduled twice a week, and an introductory rate is available for your first session. Below is how the treatment works, what it treats, how it’s priced, and why patients are increasingly choosing a medspa setting over a chiropractic or physical therapy office for it.
Why San Francisco patients are increasingly asking about this treatment
San Francisco’s population skews toward exactly the profile that tends to develop overuse tendon pain: a physically active city with a large running and cycling community, a workforce spending long hours at a desk or laptop that stresses the neck, shoulders, and elbows, and famously steep hills that place repetitive strain on the calves, Achilles tendons, and plantar fascia during an ordinary commute. Add a culture that generally favors non-surgical, lower-downtime options when they’re available, and it’s a city where a treatment like StemWave tends to have an unusually good fit with the kinds of chronic pain patients are already dealing with.
What is acoustic shockwave therapy?
Acoustic shockwave therapy, or ESWT, delivers focused acoustic pulses into painful or overused tissue. Those pulses trigger a natural healing response that helps reduce pain, restore mobility, and support tissue recovery, all without surgery, injections, or downtime. StemWave is the specific device and protocol used at Laser Clear Skin for this treatment.
Acute vs. chronic pain: why the distinction matters for treatment choice
Acute pain, a fresh sprain, a sudden strain, an injury from days ago, generally responds well to the classic rest, ice, and time approach, since the tissue is in the early, active phase of healing and mostly just needs protection while that happens. Shockwave therapy isn’t typically the first tool for a brand-new acute injury.
Chronic pain is different. If discomfort has persisted for six weeks or more despite rest, or keeps returning as soon as you resume normal activity, the tissue has likely settled into the degenerative pattern described below, and simply continuing to rest often stops producing further improvement. This is the pain profile StemWave is generally used for: not a fresh injury, but a stuck one. If you’re not sure which category your pain falls into, that’s exactly the kind of question a consultation is meant to answer before any treatment begins.
What causes chronic tendon and soft tissue pain
Most of the conditions StemWave treats aren’t simple inflammation that resolves with a few days of rest. They’re degenerative changes in the tendon, sometimes called tendinosis rather than tendinitis, where repeated stress outpaces the tissue’s ability to repair itself. Microscopic collagen fibers become disorganized, blood flow to the area is often poor to begin with (tendons are less vascular than muscle), and the normal healing cascade stalls out. This is exactly why rest alone frequently isn’t enough: without a fresh stimulus, the tissue can stay stuck in that same disorganized, under-repaired state indefinitely, which is what turns an overuse injury into a chronic one.
The science of acoustic shockwave therapy
Focused acoustic pulses delivered into tendon or soft tissue create controlled microtrauma at a cellular level, similar in concept to how microneedling works on skin, but targeting deeper structures. That microtrauma does two things clinically: it appears to restart the stalled healing cascade described above, prompting new blood vessel formation (neovascularization) and collagen remodeling in the treated area, and for calcific conditions like some cases of rotator cuff tendinitis, it can help break up calcium deposits so the body can gradually reabsorb them.
There’s also an immediate pain-relief effect that many patients notice within the first session, which is thought to relate to how the acoustic pulses affect pain-signaling nerve fibers in the treated area, sometimes described in terms of “gate control” pain theory. That’s a separate mechanism from the longer-term tissue-healing effect, which is why patients often feel some relief right away but need the full session series for the deeper structural improvement.
Conditions StemWave treats
Plantar fasciitis and heel pain: one of the most common reasons patients seek out shockwave therapy. Plantar fasciitis involves degeneration of the thick band of tissue connecting your heel to your toes, often causing sharp pain with the first steps in the morning. It’s common in runners, people who stand for long shifts, and anyone with tight calves or unsupportive footwear.
Achilles tendinopathy: chronic pain and stiffness in the Achilles tendon, often worse after periods of rest and easing slightly with movement, then worsening again with activity. Common in runners and anyone who has recently increased training intensity.
Tennis elbow (lateral epicondylitis): pain on the outer elbow from overuse of the forearm extensor tendons, not limited to tennis players, this is common among anyone doing repetitive gripping or typing-heavy work.
Golfer’s elbow (medial epicondylitis): the mirror-image condition on the inner elbow, from overuse of the forearm flexor tendons.
Patellar tendinopathy, or jumper’s knee: pain just below the kneecap, common in athletes involved in running or jumping sports, and in anyone with a sudden increase in lower-body training load.
Hamstring or gluteal tendinopathy: deep pain near the sit bone that often worsens with sitting for long periods or during running and lunging movements.
Shoulder calcific tendinitis and rotator cuff overuse: pain and restricted movement from calcium buildup or chronic overuse in the rotator cuff tendons, this is one of the conditions where shockwave’s calcium-breakdown effect is particularly relevant.
Shin splints and medial tibial stress: pain along the inner shin common in runners and anyone increasing impact activity too quickly.
Myofascial trigger points: localized, tender knots in muscle tissue that can refer pain to other areas of the body.
Back and neck pain: StemWave is FDA cleared for treatment at the C2 vertebra and below for appropriate soft tissue and myofascial pain in this region.
Accurate diagnosis matters. For complex cases, Laser Clear Skin may coordinate care with your primary care provider, physical therapist, or orthopedist.
What a session feels like
A gel is applied to the treatment area, and focused acoustic pulses are delivered for about 2 to 5 minutes per area. Intensity is adjusted so you can stay relaxed and comfortable throughout. A full visit takes about 15 minutes, and most patients return to normal activity immediately afterward, aside from avoiding unusually strenuous exercise for 24 to 48 hours.
The treatment series
Most patients complete 6 to 10 sessions, scheduled twice a week. By the third session, inflammation is usually calmed and the device is actively promoting healing by recruiting the body’s own repair cells to the area. According to Laser Clear Skin’s own clinical materials, tendon healing times can improve by up to 50% with a full course of treatment.
Why a medspa setting instead of physical therapy or chiropractic care alone
Shockwave therapy is widely available through sports medicine, chiropractic, and physical therapy practices in San Francisco. What’s different about getting it at an RN-led medspa:
- RN-led, physician-supervised care for every session, with the same clinical screening standards used across the clinic’s other treatments
- A no-risk guarantee: if you don’t notice results after your first treatment and choose not to continue, you get your money back
- A built-in credit system: a portion of what you spend on skincare, supplements, fragrance, or other aesthetic services can be applied as credit toward StemWave sessions, ask your provider for current terms
- No downtime, so a session fits into a lunch break rather than requiring a separate recovery day
Frequently misunderstood aspects of shockwave therapy
“It’s the same as ultrasound therapy.” They’re not the same. Ultrasound uses sound waves for mild heating and relaxation; acoustic shockwave therapy delivers a much more targeted mechanical pulse specifically intended to stimulate tissue repair and, in some cases, break up calcific deposits.
“If one session doesn’t fix it, it won’t work.” A single session can provide some relief, but the tissue-remodeling effect that produces lasting change is cumulative and generally requires the full 6 to 10 session series, similar to how physical therapy or strength training take a series of sessions to produce durable change, not just one visit.
“It’s only for athletes.” While sports injuries are a common reason patients seek this treatment, plantar fasciitis, shoulder pain from desk work or repetitive strain, and general tendon overuse affect plenty of non-athletes, and respond to the same mechanism.
“Shockwave therapy is a substitute for diagnosis.” It isn’t. Accurate diagnosis of what’s actually causing your pain matters before starting any treatment, which is why Laser Clear Skin may coordinate with your physician, physical therapist, or orthopedist for complex or unclear cases rather than treating symptoms blindly.
How StemWave is priced in San Francisco
Pricing shifts often enough across providers that we’re not publishing specific numbers here, a figure that’s accurate today can be stale within months. What’s worth knowing about the structure:
- An introductory rate is available for your first session, priced lower than a standard visit so you can try the treatment before committing to a full series.
- Standard sessions are priced by area, with additional areas treated in the same visit added at a lower incremental cost than the first area.
- Multi-session packages carry increasing discounts as the package size grows, rewarding commitment to the full course rather than booking one session at a time.
For current numbers, see the Membership & Packages page, or ask at your consultation.
The RN-led difference in pain management care
Acoustic shockwave therapy is available at a wide range of practice types in San Francisco, from sports medicine clinics to chiropractic offices to physical therapy practices. What’s different about receiving it at an RN-led medspa is the screening and oversight wrapped around the treatment itself. Every patient goes through a review of medications, implants, and clot risk factors before treatment, the same clinical screening standard used across Laser Clear Skin’s other services, rather than a brief intake form. For patients managing pain alongside other health conditions, having that level of screening built in adds a layer of safety that isn’t universal across every setting offering shockwave therapy.
Who’s a good candidate (and who isn’t)
Good candidates typically have persistent tendon, joint, or soft tissue pain that hasn’t improved with rest, an overuse injury from sports, repetitive activity, or work strain, or want post-surgical healing support to improve mobility. Laser Clear Skin can also safely treat over surgical implants such as knee replacements.
A few conditions call for pausing treatment, and it’s worth understanding why each one matters:
- Pacemakers or defibrillators: acoustic pulses near these devices haven’t been established as safe, so treatment is avoided as a precaution.
- Pregnancy: as a general precaution common across most energy-based treatments, given limited safety data in this population.
- Active cancer: stimulating tissue growth and blood flow in or near an active malignancy is avoided out of caution.
- Active infection or open wounds at the treatment site: treating over compromised skin or active infection could worsen the underlying issue.
Every patient is screened carefully before treatment begins, and your provider will walk through your specific history at your first visit.
Results and timeline
Many patients feel pain relief immediately, often after their very first session, though optimal results typically build after completing a full 6 to 10 session series. Some mild soreness for a day or two is normal, but there’s no redness and no real downtime involved.
- Session 1: many patients notice some pain relief right away, thought to relate to the acoustic pulses’ effect on pain-signaling nerves, separate from the deeper tissue healing that’s just beginning.
- Sessions 2–3: inflammation is usually calmed by this point, and the treatment is actively recruiting the body’s own repair cells to the area.
- Mid-series (sessions 4–6): many patients notice reduced morning stiffness and less pain during their previously aggravating activity.
- End of series (sessions 7–10): this is typically when the fullest improvement in mobility and comfort shows up, reflecting the cumulative tissue remodeling built across the whole course.
- After treatment: tendon healing is a gradual biological process, so some patients continue to notice incremental improvement for weeks after their last session.
Why rest and over-the-counter approaches often aren’t enough
It’s a common and frustrating pattern: rest the area, take an anti-inflammatory, maybe try a brace or new shoes, and the pain improves slightly, only to return as soon as normal activity resumes. This isn’t a failure of willpower or a sign you’re not resting enough. As covered above, many of these conditions involve degenerative tendon changes rather than simple inflammation, and degenerative tissue generally doesn’t rebuild itself just from being left alone. Rest removes the aggravating stress, which is necessary, but it doesn’t necessarily supply the fresh healing stimulus the tissue needs to actually remodel. That’s the gap shockwave therapy is designed to close.
How shockwave therapy compares to other pain treatment options
Rest, ice, and NSAIDs. These manage symptoms but don’t necessarily resolve the underlying tendon changes behind chronic pain. StemWave is aimed at triggering the tissue’s own repair process rather than just masking discomfort.
Cortisone injections. Cortisone can reduce inflammation and pain quickly, but effects are often temporary and repeated injections can weaken tendon tissue over time. Shockwave therapy takes longer to build results but works by stimulating repair rather than suppressing inflammation.
Physical therapy alone. Targeted exercise and stretching remain an important part of recovery for most tendon conditions, and many patients use shockwave therapy alongside physical therapy rather than instead of it.
Surgery. Surgical intervention is generally reserved for cases that don’t respond to conservative treatment. Shockwave therapy is a non-surgical option worth trying first for most tendon and soft tissue conditions, with no incision and no recovery period to plan around.
Orthotics and bracing. These can reduce the mechanical stress that’s aggravating a condition like plantar fasciitis, and are often used alongside shockwave therapy rather than as a standalone fix, since they manage the cause of strain without directly stimulating tissue repair.
Is shockwave therapy right for you? A self-check
A few honest questions can help you gauge whether this is worth exploring at a consultation:
- Has your pain lasted more than 6 weeks despite rest, stretching, or over-the-counter pain relief?
- Does the pain flare up predictably with certain activities, like the first steps in the morning, or after sitting for a while?
- Have you already tried a brace, orthotic, or change in footwear without full relief?
- Are you hoping to avoid, or delay, a cortisone injection or surgical consultation?
- Do you have any pacemaker, active cancer diagnosis, or are you currently pregnant?
If you answered yes to several of the first four and no to the last, StemWave is worth discussing with a provider. If any of the last question’s conditions apply to you, let your provider know so they can guide you toward the right option.
What to expect between sessions
Because a full course runs twice a week for several weeks, most patients notice a gradual pattern rather than an overnight fix: some pain relief after session one, less morning stiffness by the middle of the series, and the fullest improvement in mobility and comfort after the last session. Staying consistent with the twice-weekly schedule matters, since spacing sessions too far apart can slow the cumulative healing response the treatment is built around.
Between visits, most patients are told to avoid unusually strenuous exercise on the treated area for 24–48 hours, but otherwise continue normal daily activity. If you’re also doing physical therapy or a home stretching routine, your provider can help you sequence that alongside your StemWave sessions.
Typical session count by condition
While every treatment plan is individualized after assessment, these are general starting points patients often ask about by condition:
- Plantar fasciitis: often responds within a standard 6 to 8 session course, given its high prevalence in shockwave therapy research and clinical use.
- Tennis or golfer’s elbow: commonly treated across 6 to 10 sessions, with many patients noticing functional improvement (better grip, less pain with daily tasks) partway through the series.
- Achilles or patellar tendinopathy: often benefits from the fuller 8 to 10 session course, since these tendons bear significant load during daily activity and athletic movement.
- Shoulder calcific tendinitis: session count can vary more here depending on the size of calcific deposits, your provider will set expectations after assessment.
- Myofascial trigger points: sometimes respond in a shorter course, though this varies significantly by individual presentation.
These are general patterns, not guarantees. Your specific plan is set after your provider assesses your condition, history, and how you’re responding as treatment progresses.
Building StemWave into a broader recovery plan
Shockwave therapy tends to work best as part of a plan rather than a standalone fix, particularly for conditions tied to a specific movement pattern or activity, like a runner’s Achilles or a golfer’s elbow. Many patients pair their sessions with targeted stretching or strengthening from a physical therapist, adjustments to footwear or ergonomics, and a gradual, supervised return to the activity that aggravated the injury in the first place. Your provider can help you sequence this, for example, easing back into higher-impact activity as your session series progresses rather than all at once.
What your first visit looks like, start to finish
- Intake and history. Your provider reviews your pain history, what’s been tried already, and any relevant imaging or diagnoses, then screens for contraindications like pacemakers, pregnancy, or active cancer.
- Assessment. The specific area is examined and mapped so the treatment can be targeted precisely rather than applied generally.
- Same-day treatment. Because sessions are quick and low-risk, most patients begin treatment the same day as their consultation rather than scheduling a separate first appointment.
- The session itself. Gel is applied and acoustic pulses are delivered for 2 to 5 minutes per area, with intensity adjusted so you stay comfortable throughout.
- Wrap-up. Your provider discusses what to expect over the next 24 to 48 hours and schedules your next session as part of your series.
Preparing for your first session
- Wear clothing that allows easy access to the treatment area (shorts for knee or shin issues, a sleeveless top for shoulder or elbow issues)
- Bring a brief history of the pain: when it started, what makes it better or worse, and any imaging or diagnoses you already have
- Let your provider know about any pacemaker, defibrillator, pregnancy, active cancer, or open wounds near the treatment area before your session
- Plan to arrive a few minutes early for your first visit so there’s time for a proper assessment before treatment begins
Who typically refers patients to shockwave therapy
Because it sits at the intersection of pain management and non-surgical recovery, StemWave patients arrive through a few different paths. Some come directly after researching non-surgical options for a condition they’ve already been diagnosed with by a physician. Others are referred by a physical therapist whose exercise-based treatment has plateaued and who wants to add a tissue-stimulating therapy alongside continued PT. Some come from an orthopedist as a step to try before considering more invasive options like injections or surgery. And some simply come on their own, having dealt with nagging pain for months and wanting a non-surgical option to explore before escalating care.
You don’t need a referral to book at Laser Clear Skin, but if you’re already working with a physical therapist, chiropractor, or physician, it’s worth mentioning that during your consultation so your StemWave sessions can be sequenced sensibly alongside whatever else you’re doing for the same issue.
Consistency and cost-effectiveness
Because the treatment’s effect is cumulative, spacing sessions out inconsistently, skipping weeks here and there, tends to blunt the results relative to sticking with the recommended twice-weekly cadence. From a pure cost-effectiveness standpoint, a full course completed on schedule is generally a better use of the money spent than a partial course stretched out or abandoned early, since much of the structural improvement described earlier in this guide builds specifically toward the later sessions in the series. If scheduling twice a week is genuinely difficult for your routine, it’s worth discussing that directly with your provider rather than skipping sessions unpredictably, they may be able to adjust your plan’s cadence while still working toward a complete course.
Signs you should see a doctor first, before shockwave therapy
Shockwave therapy is built for chronic, overuse-type tendon and soft tissue pain, not every kind of pain. A few warning signs point toward a doctor’s visit or urgent evaluation first, rather than booking a shockwave session:
- Sudden, severe pain after a specific injury, especially with visible swelling, bruising, or deformity
- Numbness, tingling, or weakness in the affected limb, which can point to a nerve issue rather than a tendon issue
- Fever, redness, or warmth at the painful area, which can indicate infection
- Inability to bear weight or use the limb at all
- Pain following a fall or trauma that hasn’t been evaluated with imaging
None of these are reasons to panic, but they are reasons to get an accurate diagnosis before starting any treatment, including shockwave therapy. A good provider will ask about these directly during your intake and refer you out if something doesn’t fit the profile of a typical overuse tendon condition.
Glossary: shockwave therapy terms worth knowing
- ESWT: extracorporeal shockwave therapy, the clinical name for the category of treatment StemWave falls under; “extracorporeal” simply means the energy is applied from outside the body.
- Tendinopathy: a general term for tendon dysfunction and pain, often used instead of “tendinitis” because most chronic cases involve degenerative changes rather than pure inflammation.
- Tendinosis: degenerative changes within a tendon at the cellular level, distinct from acute inflammation, and the underlying issue in many chronic tendon pain cases.
- Calcific tendinitis: a condition where calcium deposits build up within a tendon, most commonly in the shoulder, contributing to pain and restricted movement.
- Myofascial trigger points: localized, tender areas within muscle tissue that can cause pain locally or refer pain to other areas of the body.
- Neovascularization: the formation of new small blood vessels in tissue, one of the repair mechanisms shockwave therapy is thought to help stimulate.
Frequently asked questions
What is StemWave shockwave therapy?
StemWave is a type of acoustic shockwave therapy (ESWT) that delivers focused acoustic pulses to stimulate healing, reduce pain, and restore mobility in tendon and soft tissue conditions, without surgery.
What conditions can shockwave therapy help with?
Common uses include plantar fasciitis, Achilles tendinopathy, tennis elbow, golfer’s elbow, patellar tendinopathy, rotator cuff overuse, shin splints, myofascial trigger points, and back or neck pain at or below the C2 vertebra.
How many sessions will I need?
Most treatment plans include 6 to 10 sessions, scheduled about twice a week, for lasting relief.
Does shockwave therapy hurt?
Intensity is adjusted throughout so you can stay relaxed and comfortable. Some patients notice mild soreness for a day or two afterward, but there’s no downtime.
Is shockwave therapy safe for everyone?
It isn’t recommended for patients with pacemakers or defibrillators, during pregnancy, for individuals with active cancer, or over active infection or open wounds. Every patient is screened before treatment to confirm candidacy.
How much does StemWave cost in San Francisco?
An introductory rate applies to your first session, with standard per-area pricing after that and increasing discounts on multi-session packages. Since pricing shifts across providers, check the Membership & Packages page or ask at your consultation for current numbers.
Is shockwave therapy covered by insurance?
Coverage varies by plan and provider. Check directly with your insurer about acoustic shockwave therapy or ESWT coverage for your specific condition before booking if this affects your decision.
How is StemWave different from a cortisone injection?
Cortisone reduces inflammation quickly but the effect is often temporary and repeated use can weaken tendon tissue over time. StemWave works more gradually by stimulating the body’s own repair process, with results building across a full session series rather than a single visit.
Can I keep exercising while getting StemWave treatment?
Often yes, in modified form. Most patients are advised to avoid unusually strenuous activity on the treated area for 24 to 48 hours after each session, but otherwise continue daily activity. Your provider can help you sequence a gradual return to your usual training or activity level alongside your session series.
What happens if StemWave doesn’t work for me?
Laser Clear Skin offers a no-risk guarantee: if you don’t notice results after your first treatment and choose not to continue, you get your money back. If a full series doesn’t resolve your pain, your provider can help you consider next steps, which may include physical therapy, further diagnostic imaging, or a referral to an orthopedist.
