What Is Shockwave Therapy and Does It Actually Work?

You’ve probably heard someone singing the praises of shockwave therapy. Maybe your running mate swears it cured their Achilles pain, or you’ve seen it advertised at clinics across Liverpool and Chester. But you’ve also probably heard stories of people who paid good money for it and saw absolutely no improvement.

So what’s the actual deal? Does shockwave therapy work, or is it just expensive noise?

Here’s the honest answer: shockwave therapy has strong evidence for specific tendon conditions, but it’s not magic, it’s not comfortable, and it absolutely won’t work if you’re expecting it to fix your problem without any effort on your part. Anyone selling it as a quick fix that replaces proper rehab is talking rubbish.

Let me break down what shockwave therapy actually is, what the evidence says it works for, and how to know if it’s right for you.

What Shockwave Therapy Actually Is

First things first — shockwave therapy is not ultrasound, it’s not TENS, and it’s not “vibration therapy.” It’s a mechanical stimulus delivered via high-energy acoustic waves that penetrate deep into tissue. Think of it like controlled, focused impact.

There are two main types: radial (the more common one, using a handheld device with a piston that generates pressure waves) and focused (more targeted, deeper penetration, usually more expensive). In most physio clinics — including mine here in Chester — you’ll encounter radial shockwave.

The device delivers rapid pulses of pressure to the affected area. What this does at a tissue level is stimulate blood flow, trigger a mild inflammatory response (which sounds bad but is actually part of healing), and potentially influence pain perception through something called gate control theory. It may also help break down calcifications in certain conditions.

What it doesn’t do: “break up scar tissue” in the way most people imagine. Tendons don’t scar like skin does, and the idea that shockwave mechanically breaks apart adhesions is oversimplified. What it likely does is stimulate a healing response in chronically unhappy tissue that’s stopped responding to normal loading.

Which Conditions Have Strong Evidence

The research isn’t equally positive for everything. Here are the conditions where multiple high-quality studies show shockwave therapy can genuinely help (Speed, 2014):

Notice a pattern? These are all chronic tendon problems — tissue that’s been unhappy for months, not acute injuries that happened last week. The effectiveness relates to how shockwave targets the tendon healing continuum (Cook & Purdam, 2009).

For other conditions like patellar tendinopathy (jumper’s knee), gluteal tendinopathy, and some types of shin pain, the evidence is more mixed. It might help, but it’s not as consistently effective as the conditions listed above.

Condition	Evidence Level	Typical Sessions
Plantar fasciitis	Strong	3–5
Calcific shoulder tendinopathy	Strong	3–5
Achilles tendinopathy	Moderate	4–6
Tennis elbow	Moderate	3–5
Patellar tendinopathy	Emerging	4–6

What a Session Actually Feels Like

Let’s be honest about this: shockwave therapy is not relaxing. It’s not a massage. It’s uncomfortable, and depending on how sensitive your tissue is, it can be downright painful.

I see a lot of patients in Chester and Liverpool who come in expecting something gentle because they’ve heard it’s “just shockwave.” Then the treatment starts and they realize this is proper mechanical work. You’ll feel a rapid tapping or pounding sensation, and the intensity builds. Most devices let you control the intensity, and we’ll work up to a level that’s challenging but tolerable.

The goal is to stress the tissue enough to trigger a healing response, which means it needs to be uncomfortable. If it feels like nothing, it’s probably doing nothing. That said, you shouldn’t be white-knuckling through it — there’s a difference between therapeutic discomfort and unnecessary suffering.

After a session, you might feel a bit sore or achy, similar to post-exercise muscle soreness. This usually settles within 24-48 hours.

How Many Sessions and How Often

Here’s the typical protocol for shockwave therapy:

One thing that frustrates me about how shockwave is sometimes marketed: people think they’ll walk out of one session pain-free. That’s not how tissue adaptation works. You’re triggering a biological process that takes weeks to unfold. If someone’s promising instant results, they’re either lying or treating a condition that would’ve got better anyway.

When Shockwave Isn’t Appropriate

There are several situations where shockwave therapy is either unsafe or unlikely to help:

Acute injuries — If you rolled your ankle yesterday or strained your calf last week, shockwave isn’t the answer. It’s for chronic conditions that have been around for at least 6-12 weeks and haven’t responded to standard treatment.

Over bony prominences or near nerves — Treating directly over bones or areas with superficial nerves can be painful and potentially harmful. A good physio will know where not to apply it.

Certain medical conditions — If you’re pregnant, have a pacemaker, take blood thinners, or have local infection or cancer, shockwave is contraindicated. Always disclose your full medical history.

As a first-line treatment — For most tendon problems, you should try proper loading exercises, activity modification, and time before resorting to shockwave. It’s not the first thing I reach for — it’s what I consider when standard approaches aren’t cutting it.

Cost and Availability

Shockwave therapy is often an add-on service, and pricing varies. Some clinics include it in standard treatment sessions, others charge extra. At my clinic, it’s integrated into our treatment plans when appropriate, rather than sold separately — because again, it’s not a standalone solution.

Expect to pay anywhere from £40-80 per session if it’s offered as a separate service, though this varies across Cheshire and Cheshire. If someone’s quoting dramatically more than that, ask what you’re paying for. The device matters (some are better quality than others), but mostly you’re paying for the physio’s expertise in knowing when and where to use it.

The Bottom Line: Does It Work?

For the right condition, used in the right way, combined with progressive loading — yes, shockwave therapy can genuinely help. The evidence for plantar fasciitis, Achilles tendinopathy, tennis elbow, and calcific shoulder tendinopathy is solid.

But it’s not magic. It won’t fix everything. And it definitely won’t work if you’re using it as an excuse to avoid proper rehab.

If you’re dealing with a chronic tendon problem that hasn’t responded to standard treatment, it’s worth discussing with a physio who understands both the evidence and the limitations. That conversation should include what exercises you’ll be doing alongside it, what realistic outcomes look like, and how many sessions you might need.

And if someone promises you’ll be cured in one session with no effort required? Walk away.

When to Get Help

If you’ve been dealing with persistent tendon pain for more than a few weeks, it’s worth getting a proper assessment rather than guessing what’ll work. A good physio can help you figure out whether shockwave therapy makes sense for your specific condition, or whether you’d be better off with a different approach.

Not sure how many physio sessions you’ll need? That’s a conversation worth having early, so you know what you’re committing to.

If you’re in the Chester, Liverpool, or North Wales area and want to talk through whether shockwave therapy might help your situation, get in touch. I’ll give you an honest answer based on what the evidence says, not what sells best.
