Shockwave Therapy for Achilles Tendinopathy: Does It Work?

Achilles tendinopathy is pain and stiffness in the Achilles tendon, the thick band of tissue connecting your calf muscles to your heel bone. It typically shows up as stiffness and pain first thing in the morning or after rest, easing slightly once you're moving, then often flaring again after running, jumping or prolonged standing.

It's usually a response to load the tendon isn't coping with — a sudden increase in running or training volume, a change in footwear, or tight, under-conditioned calf muscles are all common contributors.

Extracorporeal shockwave therapy (ESWT) delivers focused acoustic pulses through the skin into the affected tendon using a handheld probe. The aim is to stimulate blood flow and trigger the body's natural tissue-remodelling response in a tendon that has stalled in a degenerative, poorly-organised healing state rather than a straightforwardly inflamed one.

It's typically considered for Achilles tendinopathy that's been present for several months and hasn't responded to rest, calf-loading exercises, and footwear or training adjustments — what's often called "refractory" tendinopathy.

NICE has reviewed extracorporeal shockwave therapy for Achilles tendinopathy and its current guidance supports its use for this condition, provided normal arrangements are in place for clinical governance, consent and audit (NICE guidance HTG426).

It isn't a guaranteed fix for everyone, and improvement tends to build gradually over several weeks rather than appearing immediately, but for tendinopathy that's plateaued on conservative treatment alone, it's a reasonable next step before considering more invasive options.

A shockwave session takes around 20–30 minutes, including a check of your tendon, calf and gait beforehand. Most people describe the treatment itself as uncomfortable rather than painful, and it's normal to feel some soreness in the area for a day or so afterwards.

We typically recommend a course of three sessions spaced roughly a week apart, alongside a progressive calf-loading programme, since shockwave works best when it's supporting active rehab rather than replacing it. See our pricing page for current session and course rates.

For some people, tightness through the calf is part of what's keeping the tendon overloaded. Where that's the case, we may add clinical massage to a shockwave course to help that tissue move more freely between sessions, rather than treating the tendon in isolation.

Shockwave isn't suitable for everyone. We wouldn't normally use it during pregnancy, over an area with a suspected fracture, tumour or infection, if you have a bleeding or clotting disorder or are on strong blood-thinning medication, or if you've had a steroid injection in the treatment area within the last four to six weeks. We'll screen for these during your assessment before starting any course.

Shockwave therapy is a well-evidenced option for Achilles tendinopathy that hasn't responded to the basics, but it works best as part of a plan that also addresses calf strength, load and training habits, not as a stand-alone fix. If your Achilles pain has stopped responding to rest and stretching, an assessment is the best place to start.
