Tennis Elbow, Plantar Fasciitis and Achilles Pain London 2026. Why Steroid Injections Can Make Tendons Worse, and What the Evidence Supports Instead
Last updated July 2026. Medically reviewed by GMC-registered doctors at The Online GP by The Wellness.
Tendon problems are where injections are most often given and most often the wrong choice. London pricing runs to £950 for advanced autologous injections, £695 for guided injections around the spine and pelvis, £550 for hydrodistension and £250 to £320 for standard ultrasound-guided corticosteroid, with consultation, scan and procedure packages from £470. The evidence, though, is that corticosteroid in tendon problems buys short-term relief at the cost of worse outcomes a year later, and in the Achilles it is avoided altogether because of rupture risk. At The Online GP by The Wellness, doctor-performed ultrasound starts from £795 with same-day interpretation, and PRP for tendons through The London PRP Clinic by The Wellness starts from £595, against £950 for comparable autologous treatment elsewhere in London. Book and pay online in minutes, with same-day appointments across London.

Tendinopathy is not inflammation, and that changes everything
For decades these conditions were called tendinitis, the suffix implying inflammation, and treatment followed the name. Tissue studies changed the picture. What is found in a chronically painful tendon is not an inflammatory infiltrate but disorganised collagen, increased ground substance and abnormal blood vessel and nerve ingrowth. The correct term is tendinopathy, and it describes a failed healing response rather than an inflamed one.
That single fact explains why anti-inflammatory strategies underperform in these conditions and why loading does the opposite. Tendons remodel in response to controlled mechanical load. Rest weakens them, and it is why "rest it for six weeks" so reliably produces a tendon that hurts again within days of returning to activity.
The three that fill clinics are lateral epicondylitis at the elbow, plantar fasciopathy under the heel, and Achilles tendinopathy, and they behave according to the same rules.
What the evidence says about steroid injections in tendons
This is the part that saves people money and tendon quality, and it is not widely explained.
In lateral epicondylitis, the landmark randomised evidence found that corticosteroid injection produced excellent short-term relief at four to six weeks, and then substantially worse outcomes at one year than either physiotherapy or simply waiting, with markedly higher recurrence rates. The short-term win reverses.
In plantar fasciopathy, steroid gives real relief for weeks to a couple of months, with recognised risks including fat pad atrophy under the heel and, uncommonly, rupture of the plantar fascia. It has a role in severe pain that is blocking rehabilitation, and it is not a treatment strategy on its own.
In the Achilles, injection of corticosteroid into or around the tendon is generally avoided, because of the association with tendon rupture in a structure that carries several times body weight with every step.
None of this makes steroid useless. It makes it a tool for buying a window of comfort in which to load the tendon properly, rather than the treatment itself. A clinic that offers an injection without a loading plan is selling you the first six weeks and none of the next fifty.

What does work, in order
Progressive loading is the foundation, and the evidence for it is stronger than for anything injected. Eccentric and heavy slow resistance programmes remodel tendon over twelve weeks and beyond, and adherence predicts outcome more than any other variable. It is unglamorous, it is uncomfortable in the early weeks, and it works.
Load management sits alongside it. That means reducing the aggravating spike rather than stopping altogether, correcting a training error, changing grip size or racquet tension for the elbow, and addressing footwear and calf flexibility for the heel and Achilles.
Where pain blocks that work, targeted intervention has a place. Platelet rich plasma has its strongest musculoskeletal evidence in exactly these conditions, with trials in lateral epicondylitis showing better outcomes than corticosteroid at six and twelve months, and evidence in plantar fasciopathy showing comparable early relief with better durability. Because PRP uses your own concentrated platelets to provoke a repair response rather than suppressing inflammation, it works with the biology of tendinopathy rather than against it.
Shockwave therapy has reasonable evidence in recalcitrant plantar fasciopathy and Achilles tendinopathy, and nitroglycerin patches, night splints and orthoses all have niche roles.
Surgery is the last resort and is needed in a small minority.
What ultrasound adds before any decision
A scan changes the plan in these conditions more often than people expect.
At the elbow it shows the common extensor origin, the degree of tendinopathy, whether there is a tear, and whether the lateral collateral ligament is involved, which changes the safety of injection entirely.
At the heel it measures plantar fascia thickness, where above around four millimetres supports the diagnosis, and it distinguishes plantar fasciopathy from a calcaneal stress fracture, fat pad atrophy, Baxter's nerve entrapment and, in the young, apophysitis.
At the Achilles it separates midportion from insertional disease, which respond to different loading programmes, identifies partial tears, retrocalcaneal bursitis and Haglund deformity, and shows neovascularisation.
It also identifies the mimics. Gout presents at the heel and the elbow. Inflammatory arthritis and spondyloarthropathy present as enthesitis at multiple sites, particularly in someone with psoriasis or bowel symptoms. A stress fracture in a runner needs offloading, not loading. Because The Online GP by The Wellness runs blood testing from the same clinic, uric acid, inflammatory markers and screening bloods are arranged in the same visit where the pattern warrants it, with a targeted blood panel from £295.
What treatment costs in London
At the specialist end, advanced autologous injections are quoted at £950, guided facet, sacroiliac and trigger point injections at £695, hydrodistension at £550, hyaluronic acid at £375 to £475, and standard ultrasound-guided corticosteroid at £250 to £320. Packages combining consultation, diagnostic scan and a single guided procedure start from £470, and patients shopping around report quotes of £600 to £1,200 spread across three or four separate appointments.
At The Online GP by The Wellness, doctor-performed ultrasound starts from £795 for a single region, including the scan, the doctor's interpretation on the day and the plan that follows from it. PRP for tendons and joints through The London PRP Clinic by The Wellness starts from £595, against the £950 commonly charged for comparable autologous treatment in London, and a course is quoted in full before you start rather than session by session.
Timelines, honestly
Tendons are slow, and unrealistic expectations are the main reason people abandon the treatment that would have worked.
Expect meaningful change in a loading programme at six to twelve weeks, not two. Expect three to six months for a well-established tennis elbow or Achilles problem to settle substantially, and expect a plantar fascia that has hurt for a year to take several months rather than weeks. PRP typically produces gradual improvement over four to eight weeks with continued gain to three months, and it is combined with loading rather than substituted for it.
The single best predictor of a good outcome is not which injection you choose. It is whether the loading programme is actually completed.

Why patients choose The Wellness
The Online GP by The Wellness is a doctor-led private medical group in London. Tendon problems are scanned and interpreted by a GMC-registered doctor in the same appointment, so the diagnosis, the mimics and the plan are settled before anything is injected. Blood testing runs from the same clinic where gout, inflammatory arthritis or metabolic causes need excluding, PRP for tendons and joints is available through The London PRP Clinic by The Wellness from £595, and treatment is paired with a loading plan rather than sold as a standalone injection. Athletes and higher-risk patients can add the Athlete Screen at £1,695. Same-day appointments are routinely available, the group holds more than 187 five-star reviews, and appointments are booked and paid online in three taps.
Frequently asked questions
Do steroid injections work for tennis elbow? They work well for four to six weeks and then produce worse outcomes at one year than physiotherapy or waiting, with higher recurrence. Steroid is best used to create a window for loading work rather than as the treatment itself.
Can I have a steroid injection into my Achilles tendon? Corticosteroid in and around the Achilles is generally avoided because of the association with tendon rupture. Loading programmes, shockwave and PRP are the appropriate routes.
What does PRP cost for tendon problems in London? Advanced autologous injections are commonly quoted at £950 in London. Through The London PRP Clinic by The Wellness, PRP for tendons and joints starts from £595, with the course quoted in full before starting.
How long does tendon pain take to settle? Expect meaningful change at six to twelve weeks with a proper loading programme, and three to six months for established problems. Tendons remodel slowly, and completing the programme predicts outcome more than the choice of injection.
Should I rest a painful tendon? Complete rest weakens tendon and is why pain returns as soon as activity resumes. Reduce the aggravating load rather than stopping, and replace it with progressive controlled loading.
When does heel or elbow pain need investigating rather than treating? When it involves multiple sites, comes with morning stiffness or psoriasis, follows a sudden increase in running volume, or fails sensible treatment. Gout, inflammatory arthritis and stress fractures all present this way and are identified by scan and blood testing rather than assumption.
