Extracorporeal shockwave therapy (ESWT) is a non-surgical, non-injection treatment that uses focused acoustic pressure waves to stimulate the body’s own healing response in chronically injured tendons and fascia. The technology was originally developed to break up kidney stones and later adapted for musculoskeletal medicine, where decades of clinical research have established it as an effective option for conditions that fail to respond to rest, orthotics, and physical therapy alone.

At Michigan Avenue Podiatry, shockwave therapy is available for a range of foot and ankle conditions at our Chicago office. The procedure is performed in-office in 15–20 minutes, requires no anesthesia, and allows patients to walk out the same day. Shockwave therapy is available as a cash-pay procedure at Michigan Avenue Podiatry. Contact us at (312) 701-0770 to discuss your case.

How Shockwave Therapy Works

During an ESWT session, a handheld applicator is placed against the skin over the target area — typically the heel, arch, or Achilles tendon. High-energy sound waves are delivered in focused pulses into the affected tissue. This acoustic energy creates controlled microtrauma that triggers a cascade of biological responses: increased blood vessel formation (neovascularization), release of growth factors including TGF-β1 and VEGF, and the synthesis of new collagen fibers (neocollagenesis) in the treated tissue.

The result is genuine tissue repair rather than temporary pain suppression. Unlike cortisone injections, which reduce inflammation acutely but can weaken tendon tissue with repeated use, ESWT addresses the underlying degenerative changes that characterize conditions like chronic plantar fasciitis and Achilles tendinopathy. A meta-analysis of 45 controlled studies found significant pain reduction with ESWT across multiple tendinopathy conditions (pmc.ncbi.nlm.nih.gov/PMC11041007/).

Conditions Treated with Shockwave Therapy at MAP

Michigan Avenue Podiatry uses shockwave therapy for several chronic foot and ankle conditions. Each condition has its own evidence base and treatment protocol — follow the links below for condition-specific information including clinical research, expected outcomes, and FAQ sections:

• Shockwave therapy for plantar fasciitis — the most studied ESWT application; meta-analysis data supports significant heel pain reduction vs. placebo
• Shockwave therapy for Achilles tendinitis — effective for both insertional and non-insertional Achilles tendinopathy
• Shockwave therapy for heel pain and heel spurs — addresses calcaneal spurs and plantar fascial inflammation at the insertion
• Shockwave therapy for metatarsalgia (ball-of-foot pain) — acoustic waves stimulate healing in the plantar plate and surrounding soft tissue

What to Expect at Your ESWT Appointment

Before treatment begins, ultrasound gel is applied to the skin over the treatment area. This gel serves as a coupling medium that allows acoustic waves to pass efficiently from the applicator into the underlying tissue. The applicator is then moved slowly over the target zone while delivering pulsed shockwaves at a calibrated energy level and frequency.

Most patients experience mild to moderate discomfort during treatment, often described as a tapping or vibrating sensation with brief sharp intensity at the most affected area. This discomfort is expected and indicates that the waves are reaching the target tissue — it is not a sign of harm. Patients rate ESWT discomfort at approximately 3–5 out of 10 on average.

Sessions last 15–20 minutes. A standard ESWT course consists of 3–5 sessions spaced one week apart. No anesthesia or sedation is required. Patients can walk out of the office immediately after treatment, and there are no wound care requirements or activity restrictions beyond avoiding high-impact exercise in the 24–48 hours after each session.

Some patients notice mild soreness in the treated area for one to two days after each session — this is a normal part of the healing response and should not be confused with worsening of the original condition. Improvement typically begins to be felt in weeks 2–3 of the treatment course, with full therapeutic effect continuing to develop over 6–12 weeks as tendon remodeling progresses.

Is Shockwave Therapy Right for You?

ESWT is typically recommended when conservative measures — including rest, anti-inflammatory medications, custom orthotics, and physical therapy — have not provided adequate relief over a period of 3 months or more. Good candidates for shockwave therapy include patients with:

• Chronic plantar fasciitis (heel pain present for 3+ months)
• Achilles tendinopathy (insertional or non-insertional)
• Calcaneal heel spurs causing ongoing pain
• Metatarsalgia or plantar plate inflammation not responding to conservative care
• Patients who cannot take extended time off for surgical recovery

ESWT is not indicated for patients with active infection in the treatment area, blood clotting disorders, open wounds over the target site, or certain systemic conditions. Your podiatrist will review your history and imaging before recommending the procedure.
