Quick Answer:
Quick Answer: Extracorporeal shockwave therapy (ESWT) delivers focused acoustic energy waves to stimulate tendon and bone healing through neovascularization, collagen remodeling, and substance P depletion. It is FDA-cleared for plantar fasciitis and has strong evidence for insertional and non-insertional Achilles tendinopathy, calcific shoulder tendinitis, and several other tendinopathies. ESWT is recommended for patients who have failed 3–6 months of conservative management. A course of 3–6 weekly treatments produces sustained pain relief in 70–85% of appropriate candidates. ESWT is performed in-office without anesthesia and has no recovery downtime.
If you’ve had plantar fasciitis or Achilles tendinopathy for more than 3–6 months, done the stretching, worn the orthotics, tried the cortisone, and still can’t get out of pain — extracorporeal shockwave therapy (ESWT) may be the intervention you’re missing. It’s one of the most evidence-backed treatments for chronic tendinopathy and heel pain, and it’s available without surgery, without anesthesia, and without any recovery downtime.
At Balance Foot & Ankle PLLC, Dr. Tom Biernacki offers ESWT for plantar fasciitis, Achilles tendinopathy, and other chronic foot and ankle tendinopathies at our Howell and Brighton Michigan clinics. This page explains who is a good candidate, what the treatment involves, and what outcomes you can realistically expect.
What Is Extracorporeal Shockwave Therapy?
ESWT uses an acoustic device (either focused or radial) to deliver high-energy pressure waves through the skin to injured tissue — in this case, the plantar fascia, Achilles tendon, or other affected tendons. The waves interact with the tissue at multiple levels:
- Neovascularization: stimulates new blood vessel formation in the hypovascular tendon tissue, improving oxygen and nutrient delivery
- Collagen remodeling: disrupts disorganized scar tissue and stimulates organized collagen fiber formation
- Substance P depletion: reduces the neuropeptide responsible for chronic pain sensitization at tendon insertion sites
- Calcification breakdown: breaks down calcium deposits in calcific tendinopathy (calcific heel spurs, insertional Achilles calcification)
- Growth factor release: TGF-β1, VEGF, and other growth factors are upregulated, stimulating tissue repair
ESWT is not an injection, not a surgical procedure, and not a medication. It works by stimulating the body’s natural healing cascade in tissue that has become chronically degenerated and inflammation-resistant.
Conditions Treated with ESWT
Plantar fasciitis / chronic heel pain: the most common ESWT application in podiatric practice. FDA-cleared for plantar fasciitis refractory to 6 months of conservative care. Multiple high-quality RCTs show 70–85% responder rates (≥50% pain reduction) with ESWT vs. 20–40% for sham control at 12-month follow-up. Effect is durable — improvement continues for up to 24 months post-treatment.
Achilles tendinopathy (both insertional and non-insertional): strong evidence for ESWT in mid-portion Achilles tendinopathy that hasn’t responded to eccentric loading. Particularly useful for insertional tendinopathy where eccentric exercises are limited by Haglund’s impingement. Success rates comparable to plantar fasciitis.
Calcific tendinopathy with heel spurs: ESWT specifically disrupts hydroxyapatite calcium deposits in calcific tendinopathy. Calcific heel spur resorption is documented on serial X-rays after ESWT in responsive patients.
Other applications with growing evidence: tibialis posterior tendinopathy, peroneal tendinopathy, Morton’s neuroma (low-energy), and stress fracture stimulation (though this remains investigational for foot fractures).
Who Is a Candidate for ESWT?
ESWT is appropriate for patients who have:
- Confirmed diagnosis of plantar fasciitis or Achilles tendinopathy (clinical examination + diagnostic ultrasound)
- Failed 3–6 months of adequate conservative treatment — including stretching, physical therapy, orthotics, and at least one corticosteroid injection
- No contraindications (see below)
ESWT is NOT appropriate for: active local infection, coagulopathy or anticoagulation therapy, active malignancy in the treatment area, pregnancy, and pediatric growth plates (in children). Cortisone injections should be withheld for at least 6 weeks before ESWT — recent steroid injection impairs the tissue response that ESWT aims to stimulate.
What to Expect During ESWT Treatment
Each ESWT session takes approximately 15–20 minutes. The treatment area is located with diagnostic ultrasound or clinical palpation. A coupling gel is applied to the skin, and the shockwave applicator is pressed against the heel or tendon. Treatment intensity is adjusted to the patient’s tolerance — most patients describe a deep tapping or pressure sensation, occasionally with localized discomfort at the most reactive tissue points. Local anesthesia is deliberately avoided for focused ESWT, as the pain response helps identify the most pathological tissue.
A standard course involves 3–6 weekly sessions. Many patients notice improvement beginning after session 2–3, with continued improvement over 8–12 weeks post-treatment. Running and high-impact activity is reduced for 24–48 hours after each session; there is no extended recovery requirement.
ESWT Evidence Summary
ESWT for plantar fasciitis and Achilles tendinopathy has been studied in over 50 randomized controlled trials. The evidence summary as of 2025:
- Plantar fasciitis: Class A evidence (multiple high-quality RCTs). NNT approximately 2.5 (one out of every 2–3 treated patients achieves ≥50% pain reduction who would not have improved with sham)
- Non-insertional Achilles tendinopathy: Class A evidence. Comparable to eccentric loading program at 12 months, superior at 24 months in some trials
- Insertional Achilles tendinopathy: Class B evidence (high-quality trials, fewer than mid-portion). Particularly useful when eccentric loading is limited
- Calcific tendinopathy: Class A evidence for calcification resorption and pain relief

Dr. Tom Biernacki’s Recommendation
ESWT changed my practice for chronic plantar fasciitis. Before adding shockwave, I had a subset of patients who had done everything right — orthotics, PT, stretching, 2–3 cortisone injections — and still had disabling heel pain 12–18 months in. ESWT is the intervention that reliably moves that group forward. The evidence is as solid as anything we have for plantar fasciitis, and I’ve seen patients who’ve been suffering for over a year get meaningful, lasting relief after a 4-week ESWT course. For insertional Achilles specifically — where eccentric exercises are limited by the Haglund’s compression — ESWT fills a treatment gap that nothing else adequately addresses.

Frequently Asked Questions
Does shockwave therapy hurt?
ESWT produces a deep tapping or pressure sensation — many patients describe it as uncomfortable but tolerable. The most sensitive spots are the most pathological tissue areas. Local anesthesia is deliberately not used for focused ESWT protocols because the pain response helps identify treatment targets. Treatment intensity is adjusted to your tolerance. Most patients find it significantly more comfortable than they anticipated after the first session.
Does insurance cover shockwave therapy for plantar fasciitis?
Most insurance plans do not currently cover ESWT for plantar fasciitis, despite strong clinical evidence. Some plans cover it under specific circumstances (failed 6 months of conservative care) or for specific CPT codes. We will check your specific insurance coverage when you schedule your ESWT consultation. Patients who choose to proceed out-of-pocket typically pay $200–$500 per session for a 3–6 session course.
How long before I feel results from shockwave therapy?
Many patients notice initial improvement after sessions 2–3 (weeks 2–3 of treatment). Substantial improvement typically occurs at 6–8 weeks post-treatment as collagen remodeling and neovascularization advance. Full results develop over 12 weeks post-treatment. Pain may temporarily increase slightly after the first 1–2 sessions as the inflammatory response is stimulated — this is normal and expected.
Is shockwave therapy better than surgery for plantar fasciitis?
For most patients with chronic plantar fasciitis, ESWT should be attempted before surgical intervention. ESWT has comparable or superior outcomes to plantar fascia release surgery in multiple comparative studies, with a significantly lower risk profile — no wound healing complications, no nerve damage, no fascia destabilization, and no recovery requirement. Surgery (endoscopic plantar fasciotomy) is reserved for patients who fail both maximal conservative care and an appropriate ESWT course.
