Peroneal tendinopathy is treated mainly without surgery: you adjust the activities that aggravate the tendon, wear supportive footwear, and rebuild the tendon's capacity with a graded strengthening and balance programme. NHS Borders says many people improve within 12 weeks of following this kind of advice, although some need six to nine months of focused rehabilitation to return to full activity without pain. This guide explains each step, what to do in the first days, how to progress exercises, and when a physiotherapy assessment is worth booking.
TL;DR
- Most peroneal tendon problems settle with non-surgical care: load management, supportive shoes and progressive strengthening.
- Walking is usually fine if the tendon is not red or swollen. Cut back high-impact and twisting activity for the first 4 to 6 weeks, then reintroduce it slowly.
- Start with heel raises and calf stretches, then add resisted foot work and balance training.
- Expect around 12 weeks for many people to improve, and up to six to nine months for a full return to sport.
- See a physiotherapist if there is no improvement after 12 weeks, the ankle keeps giving way, or it becomes hot, swollen and tender.

What peroneal tendinopathy is
The peroneal tendons run down the outside of the lower leg, behind the bony bump of the outer ankle, and attach to the foot. They help turn the foot outwards and steady the ankle when you walk, run or change direction. Tendinopathy means the tendon has become painful and less able to cope with load. NHS Lanarkshire describes the typical picture: pain around the outside of the ankle or foot that eases with rest and gets worse with walking, running and jumping.
You may also see the condition called peroneal tendonitis. The words are often used interchangeably by patients. Clinicians now tend to prefer "tendinopathy" because the problem is usually about how the tendon copes with load rather than simple inflammation, and that affects the treatment: rest alone rarely fixes it, while well-judged loading does.
Common signs include:
- aching or sharp pain behind or just below the outer ankle bone
- pain that is worse at the start of activity, or after a long day on your feet
- tenderness when you press along the tendon
- mild swelling or warmth in flare-ups
- a feeling that the ankle is weak or unstable on uneven ground
What causes it
Tendon pain usually appears when the demands on the tendon exceed its current capacity. NHS Borders lists the common contributors:
- overuse, or a sudden jump in activity
- repetitive walking, running or standing
- high-impact sport
- weak foot and leg muscles, or tight calves
- poor training habits or too little recovery
- unsupportive footwear
- previous ankle trauma or surgery
- diabetes, inflammatory disease and smoking
In practice, we often see it after someone returns to running too quickly, starts a new job on their feet, or has had a sprain that never fully rehabilitated. If you have had repeated sprains, our guide to what causes ankle injuries explains how the ankle's outer structures are stressed.
The first days: protect, then load
Ice, compression and elevation
If the outer ankle is sore and a little puffy after an injury or a flare-up, ice can ease pain and swelling. NHS Lanarkshire suggests a cold pack wrapped in a damp towel for 10 to 20 minutes, two or three times a day, with care to avoid numbness or skin damage and never placing ice directly on the skin. Our own article on ice after injury covers the safe way to do it.
Compression and elevation can also help swelling. If you are thinking about compression devices, check first that they suit you: this overview of compression boots contraindications lists the circumstances in which they should not be used. A simple elasticated support is usually enough for the outer ankle.
A short period of relative rest
NHS Lanarkshire advises protection and relative rest for the first 24 to 72 hours after an acute injury, followed by gradual activity rather than prolonged rest. That distinction matters. Staying off the foot for weeks weakens the tendon and calf, and the pain returns as soon as you restart.
Pain relief
If you need pain relief, speak to your GP or pharmacist about what is suitable for you. A 2022 American Academy of Family Physicians review notes that short-term paracetamol (acetaminophen) or anti-inflammatory tablets can ease pain, and that corticosteroid injections need caution because injecting a tendon may weaken it and raise the risk of rupture. Ask your clinician to explain the risks before agreeing to an injection.
Is it safe to walk on a painful peroneal tendon?
Usually yes, with care. NHS Bexley's musculoskeletal service says walking is a low-impact activity that can be continued cautiously if the tendon is not red or swollen. It suggests avoiding the most painful activities for the first 4 to 6 weeks, particularly high-impact activities and twisting, and then reintroducing exercise slowly.
NHS Borders adds that a limp can be normal early on, and you should try to put weight through the foot, but reduce long periods of walking or standing if they aggravate the pain. The My Joint Health Hub similarly recommends adjusting walking distance and the amount or intensity of activity while staying active where you can.
A practical way to apply this:
- Choose a walking distance that leaves the ankle comfortable or only mildly sore, and that has settled by the next morning.
- If pain is clearly worse the following day, reduce the distance or break it into shorter walks.
- Avoid uneven ground, hills and sudden changes of direction until the tendon tolerates flat walking.
- Increase gradually, by a small amount every few days, not in one big step.
Breaking tasks into chunks, with rests between, is what NHS Lanarkshire calls pacing and spacing. It helps people on their feet all day, such as nurses, teachers and tradespeople, who cannot simply stop.
Footwear and support
Shoes are one of the easiest things to change. NHS Borders recommends comfortable, supportive trainers or hiking boots with a slight heel, and advises avoiding hard, flat or slip-on footwear when they aggravate symptoms. NHS Lanarkshire gives similar advice on running-style trainers. Check that the heel counter holds your foot firmly and the sole is not worn on the outer edge.
Some people benefit from an insole or ankle brace to support the tendon while it recovers. A physiotherapist or podiatrist can assess your foot shape and gait and say whether that is worthwhile for you. At our centre, podiatry sits alongside physiotherapy, so footwear and biomechanics can be reviewed in the same care plan.
Exercises for peroneal tendon rehabilitation
Exercise is the core of treatment. The AAFP review says most peroneal tendinopathies respond to non-operative care combining activity modification, bracing and physical therapy with early range of motion, progressive tendon loading and balance training. The programme below follows the stages described by NHS Borders and Musculoskeletal Matters Dorset. It is general guidance, not a personal prescription. If an exercise causes sharp pain or swelling, stop and have it reviewed.
Stage 1: heel raises and calf stretches
NHS Borders starts with two-leg heel raises, up to 10 repetitions three times a day. Dorset's service suggests beginning with a small number as pain allows, then building up, with 10 repetitions for three sets as a common target. When these feel comfortable, progress to single-leg raises. Add calf stretches, because tight calves are a recognised contributor.
- Stand holding a worktop for balance.
- Rise slowly onto the balls of both feet, pause, then lower over a few seconds.
- Keep the weight even across the foot, without rolling outwards or inwards.
- Mild discomfort that settles quickly is acceptable. Pain that lingers or builds is a signal to reduce.
Stage 2: resisted foot work
Once heel raises are comfortable, NHS Borders adds resisted foot movements, typically using an elastic band around the forefoot to work the muscles that turn the foot outwards. Go slowly in both directions, because the controlled return phase is where much of the benefit lies.
Stage 3: balance and control
Musculoskeletal Matters Dorset recommends progressive balance work:
- Begin with supported weight transfer from one foot to the other.
- Progress to standing unsupported on one leg.
- Make it harder with eyes closed, arms raised, or passing a ball.
- Consider a wobble board only when the easier steps are manageable.
Balance training matters because the peroneal tendons help control the ankle on uneven ground. Rehabilitation after a sprain follows the same principles, and our ankle injury rehabilitation checklist and step by step ankle sprain rehabilitation guide give useful progressions.
Stage 4: return to impact and sport
Once single-leg raises, resisted work and balance are strong and pain-free, begin with low-level hopping, jogging on flat ground and gentle changes of direction, one new element at a time. If you run, alternate run and walk intervals and increase total time gradually. Preventing a repeat is covered in our tips to prevent ankle ligament injuries in sport.
If the Achilles is also sore, the staged approach in our Achilles tendinopathy exercises plan uses similar loading principles.
How long does recovery take?
Be realistic. NHS Borders says many people improve within 12 weeks of following its advice, but recovery varies, and some need six to nine months of focused rehabilitation before they are pain-free at full activity. Flare-ups can happen along the way and do not mean you are back at the start. Reduce the load for a few days, then resume at a slightly lower level.
South West Devon NHS referral guidance says a loading-based programme should generally run for around three months before escalation is considered. That is why consistency in the first three months matters more than any single treatment.
| Stage | Typical focus | Rough guide |
|---|---|---|
| Settling the pain | Pacing, footwear, short-term ice, relative rest after a flare | First days to 4 to 6 weeks |
| Rebuilding strength | Heel raises, resisted foot work, calf stretches | From early weeks, building over about 12 weeks |
| Balance and control | Single-leg balance, harder surfaces | Weeks to months |
| Return to sport | Graded impact, running intervals, direction changes | Up to six to nine months for some people |
These are guides, not deadlines. Tendons adapt slowly, and age, general health, work demands and how long you have had symptoms all affect the pace.
When to see a physiotherapist
Self-management suits many people, but get assessed if:
- symptoms have not started to improve after 12 weeks of following the advice
- the ankle gives way more often
- the ankle becomes hot, swollen and tender, which needs prompt medical advice because it can signal something other than simple tendon overload
- you felt a sudden snap or have lost strength after an injury, which could indicate a tear
- you cannot work out which exercises or what load to use
Those first three points come from NHS Borders. A physiotherapist will examine the tendon, check ankle and foot alignment, test strength and balance, and look at your training or work pattern. They then set a loading programme at the right level for you and progress it as you improve.
If the picture is unclear, or the tendon is not responding, imaging may help show whether there is a tear or another cause of outer ankle pain. We can refer for imaging when it is clinically appropriate. A rapid imaging referral is one of the things our patients value, and the review of results is part of the same care pathway.
Perspective: how we approach it
We see peroneal tendon pain in runners, footballers, dancers, walkers and people whose jobs keep them standing, and the pattern is consistent. People rest until the pain goes, restart at the old level, and the tendon flares again. The answer is rarely more rest. It is a plan that matches load to what the tendon can currently manage and increases it deliberately.
We also think it is worth treating the whole chain. A tight calf, weak hip, worn-out shoes or a past sprain that was never rehabilitated can all keep the peroneals overworked. Our multidisciplinary team, working since 1986, means a physiotherapist, podiatrist or sports massage therapist can look at the same problem from different sides without sending you elsewhere. Shockwave therapy may be considered for stubborn tendon problems after assessment, but only alongside, never instead of, progressive loading, and only if your physiotherapist feels it suits your case.
Our advice: start the exercises early, keep a simple diary of pain after activity, and do not wait many months before asking for help.

FAQ
How can I heal peroneal tendinopathy quickly?
There is no reliable shortcut, because tendons adapt slowly. The fastest route is to cut back aggravating load, wear supportive shoes and follow a progressive strengthening programme consistently. NHS Borders says many people improve within 12 weeks.
Should I rest completely or keep walking?
Short relative rest is sensible for the first 24 to 72 hours after an acute injury, then activity should return gradually. Walking is usually acceptable if the tendon is not red or swollen, as long as pain settles by the next day. Reduce long walks and avoid twisting movements for the first 4 to 6 weeks.
What is the root cause of peroneal tendinopathy?
Usually a mismatch between the load placed on the tendon and its capacity. Sudden increases in activity, repetitive standing or running, weak or tight muscles, unsupportive footwear and previous ankle injuries are the common contributors listed by NHS Borders.
Is a steroid injection a good option?
It is not a first-line choice. The 2022 AAFP review warns that injecting a tendon may weaken its structure and increase the risk of rupture. Discuss it with your GP or specialist, who can weigh up the risks for your situation.
