PRP vs steroid injections for Achilles tendon pain: what London runners should know
If you have had Achilles tendon pain for more than a few weeks, someone has probably offered you a steroid injection. For the Achilles specifically, that is usually the wrong offer, and knowing why could save your tendon. Steroid injections around the Achilles carry a real risk of weakening tissue that is already struggling, and tendon specialists avoid them here for good reason. PRP takes the opposite approach: rather than suppressing inflammation, it aims to support the tendon's own repair. At The London PRP Clinic by The Wellness, every Achilles is assessed by a GMC-registered doctor who will give you an honest read on what the evidence supports for your tendon.
Key points
Corticosteroid injections near the Achilles tendon are associated with tendon weakening and rupture risk, and are generally avoided by tendon specialists.
Eccentric and heavy slow resistance strengthening remains the first-line, best-evidenced treatment for Achilles tendinopathy.
PRP aims to support tendon repair rather than mask symptoms, and its safety profile is favourable; the evidence for benefit is supportive but mixed, and we say so plainly.
The strongest case for PRP is a chronic tendon that has genuinely plateaued on a proper loading programme.
Joint and tendon PRP at The London PRP Clinic by The Wellness starts from £750 per treatment area.
Why steroids and the Achilles do not mix
Corticosteroid injections are powerful anti-inflammatories, and in some joints that is useful. The Achilles is different. It is the thickest tendon in the body, it transmits enormous force with every step, and steroid injected into or around it can weaken the collagen structure further. Case series and clinical guidance have linked peritendinous steroid injections to Achilles rupture, which is a surgical injury with months of recovery. Tendon specialists have largely abandoned steroid for the Achilles, yet it is still offered to patients who are simply desperate for the pain to stop. If a clinic offers you an Achilles steroid injection without a detailed discussion of rupture risk and alternatives, ask more questions.
What actually works first
Achilles tendinopathy is a load-tolerance problem, and the best-evidenced treatment is progressive loading: eccentric heel-drop programmes and heavy slow resistance training, typically over twelve weeks or more, ideally supervised by a physiotherapist. Many tendons settle with this alone, and any honest clinic starts here. Adjuncts such as shockwave therapy have supporting evidence in some cases. What does not work long term is repeated symptom suppression: painkillers and rest make the pain quieter while the tendon gets less conditioned, so it complains again the moment you reload it.
Where PRP fits, honestly
PRP (platelet-rich plasma) concentrates the platelets from your own blood and injects them into the degenerate tendon tissue, where they release growth factors that support repair. The honest summary of the evidence: some trials show meaningful benefit in chronic Achilles tendinopathy, particularly combined with a loading programme, while a well-known 2021 placebo-controlled trial found no significant difference for midportion Achilles tendinopathy on its primary outcome. We will tell you this at consultation, because you deserve the real picture. What PRP offers that steroid does not is a favourable safety profile: it is your own blood, it does not weaken tendon collagen, and serious complications are rare. For a tendon that has plateaued despite months of proper loading, it is a reasonable next step before considering more invasive options, with expectations set accordingly.
What treatment involves
Your consultation covers history, examination, review of any imaging, and a straight answer on whether your Achilles needs better rehabilitation, PRP, shockwave, or a surgical opinion. If PRP is suitable, a small blood sample is taken, processed to concentrate the platelets, and injected into the target tissue under guidance in a single visit of around 45 minutes. You leave with a written reloading plan over six to twelve weeks, coordinated with your physiotherapist. Many cases need one or two sessions. Runners often also read about our work on Achilles and patellar tendinopathy and marathon training injuries.
What it costs
At The London PRP Clinic by The Wellness, joint and tendon PRP starts from £750 per treatment area, confirmed before any treatment begins. Consultations are £59 by phone for 15 minutes, £150 by video and £220 in person at our Marylebone clinic. If the verdict is that your tendon needs a different route, you pay only for the consultation and leave with a clear plan.

Frequently asked questions
Is a steroid injection ever right for Achilles tendon pain?
Rarely, and only in specific circumstances under specialist care. Steroid injections around the Achilles are associated with tendon weakening and rupture risk, so tendon specialists generally avoid them. If one has been offered without a detailed risk discussion, seek a second opinion first.
Does PRP definitely work for Achilles tendinopathy?
No treatment is guaranteed, and the honest answer is that evidence is supportive but mixed: several studies show benefit in chronic cases combined with loading, while a 2021 placebo-controlled trial found no significant advantage on its primary outcome. PRP's safety profile is favourable, which is part of why it is considered before more invasive options.
What is the best first treatment for Achilles tendinopathy?
A progressive loading programme, typically eccentric and heavy slow resistance exercises over twelve weeks or more, supervised by a physiotherapist. Many tendons improve with this alone, and any injection works best alongside it rather than instead of it.
How do I know if my Achilles is at risk of rupture?
Warning signs include a sudden sharp pain like being kicked in the heel, an audible snap, inability to push off or stand on tiptoe, and a palpable gap in the tendon. That is an emergency: same-day assessment, not a PRP consultation. Long-standing tendon pain does raise rupture risk modestly, which is one reason to treat it properly.
How many PRP sessions does an Achilles tendon need?
Many cases improve after one or two sessions alongside the loading programme. Longer-standing or more degenerate tendons may need a short course. Your doctor gives you a realistic expectation after examining the tendon.
How much does PRP for Achilles pain cost in London?
At The London PRP Clinic by The Wellness, joint and tendon PRP starts from £750 per treatment area. Consultations are £59 by phone for 15 minutes, £150 by video and £220 in person.
