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.

Achilles problems are one of the main reasons people are referred toward shockwave here. Alex, PhysioHub's founder and a HCPC-registered physiotherapist, treats them in Uckfield in runners whose first mile is always the worst, in mid-life recreational athletes returning to sport after a gap, and in people on their feet all day with a thickened, tender tendon. With musculoskeletal experience across the NHS and private practice, he assesses whether the tendon is mid-portion or insertional, because that changes both the loading and whether shockwave is appropriate.

Most people book after a year or more of it. They have stretched, rested, changed shoes, tried heel inserts, and stopped running altogether at some point, only for the tendon to feel just as sore when they started again. Your first appointment is a 60-minute assessment: a full history, hands-on testing of the tendon and calf, calf strength and capacity measures, and a clear explanation of where the tendon currently stands. Treatment starts on the day, and shockwave is offered where the picture fits rather than by default.

What clients get is a tendon that tolerates load again: walking the first stretch of the morning without limping, standing through a working day, and rebuilding running or sport with the calf strong enough behind it. Shockwave is used to open the door, and the loading programme is what keeps it open.

You can access this through our shockwave therapy service, available as single sessions or a course, always combined with our musculoskeletal pain and injuries assessment and a tailored loading plan, plus our gym-based 1:1 rehab and strength training sessions for the calf work that carries the result. If you are heading back to running or sport, our sports injuries and performance service covers the return, and our tendinopathy page explains the approach. Book an assessment to find out whether shockwave suits your tendon.

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.
