Extracorporeal shockwave therapy (ESWT) uses focused pressure waves to stimulate healing in damaged tendon and fascia tissue — without incisions or anesthesia. It's most often used for chronic plantar fasciitis, Achilles tendinopathy, and heel pain that hasn't improved with stretching, orthotics, or physical therapy, and it gives many patients a way to avoid surgery.
If you've been dealing with heel or Achilles pain for months and feel like you've tried everything, shockwave therapy is one of the questions we hear most often in our Farmington and South Ogden offices. Here's how it works, who is — and isn't — a good candidate, and what treatment actually involves.
How does shockwave therapy work?
During treatment, a gel is applied to the skin over the painful area, and a handheld device delivers focused pressure waves directly to the damaged tissue. Those waves increase local circulation and trigger the body's natural healing response, helping stimulate repair in tendon and fascia that has become chronically irritated and hasn't healed on its own. The procedure is done in the office, and patients are able to walk out immediately afterward — there's no downtime the way there would be with surgery.
What conditions does shockwave therapy treat?
ESWT is most commonly used for chronic, treatment-resistant cases of:
- Plantar fasciitis and chronic heel pain
- Achilles tendinopathy — ongoing irritation and thickening of the Achilles tendon
- Other chronic tendon conditions that haven't responded to first-line care
It's generally considered for pain that has lasted longer than three months and hasn't improved with conservative treatments like stretching, custom orthotics, or physical therapy — not as a first step for new or mild symptoms.
What does a course of treatment look like?
Most patients receive a series of three to six sessions, typically spaced about a week apart. Each session itself is brief, but the cumulative effect of the series is what drives healing over time. Improvement is usually gradual rather than immediate — most patients notice meaningful change somewhere between six weeks and three months after finishing treatment, as the tissue continues to remodel and heal.
What are the side effects?
Shockwave therapy is well tolerated. The most common side effects are temporary soreness, mild swelling, and bruising at the treatment site, which typically resolve within a few days. Because it's non-invasive, it avoids the risks associated with surgical incisions, anesthesia, and a lengthy recovery.
Who is — and isn't — a good candidate?
Good candidates typically have chronic foot or ankle pain that hasn't responded to stretching, orthotics, or physical therapy after a reasonable trial of conservative care. Shockwave therapy is not appropriate for everyone, however. It is generally not recommended for patients who are pregnant, taking blood thinners, or have an active infection in the treatment area. Our physicians will review your history and prior treatment to determine whether ESWT is a good fit for you.
Does shockwave therapy replace other treatment?
No — shockwave therapy works best as part of a complete treatment plan, not as a standalone fix. Shock waves don't do all of the work for you: lasting results still depend on following through with home stretching exercises, supportive footwear, and any activity modifications your physician recommends alongside treatment. Patients who combine ESWT with these habits tend to see the best long-term outcomes.
When should you consider shockwave therapy?
If you've had heel, arch, or Achilles pain for more than a few months and conservative measures like rest, stretching, and orthotics haven't resolved it, it's worth discussing shockwave therapy with a podiatrist before considering surgery. Our physicians can evaluate your specific condition and let you know whether ESWT — or another treatment — is the right next step. You can request an appointment at either of our Northern Utah offices.
