Sprained Ankle Treatment & Physiotherapy: How to Treat It Properly

What is an ankle sprain?

A sprain — often called a "twisted ankle" — is an overstretch or tear of ligaments — most often on the outside of the ankle after the foot rolls inwards. Severity is graded 1 (stretch) to 3 (complete tear), and the NHS sprains guidance covers when to be checked: inability to take four steps, bone tenderness, numbness or a foot pointing the wrong way all mean hospital, not home treatment — some "sprains" are fractures needing surgery. Everything on this page is general ankle treatment for the common lateral ankle sprain; it isn't the right protocol for a foot sprain further forward. Pain and swelling centred over the middle of the foot rather than around the ankle bones — especially after a twisting fall or a direct blow, and worse pushing off when walking — points to a midfoot (Lisfranc) sprain, which needs an X-ray rather than home rehab, because missed midfoot injuries heal badly. If in doubt about which it is, get it looked at rather than guessing. If you haven't yet ruled out a fracture, my sprain or fracture self-check walks through that first.

The first 72 hours: protect, don't entomb

• Relative rest and elevation. Up on a chair or cushions, above heart level when possible.
• Ice 15–20 minutes at a time, a few times daily, with a cloth barrier — for comfort more than cure.
• Compression — a tubular bandage during the day helps swelling and confidence.
• Early gentle movement. From day 1–2: draw slow circles and up/down movements within tolerable discomfort. Immobilised ankles stiffen and weaken fast.
• Walk as pain allows. Weight-bearing early — even partially, even ugly — consistently speeds recovery in the research versus strict rest.

What I'd avoid early

• Heat, alcohol and vigorous massage in the first couple of days (all can increase swelling).
• "Testing it" with sport before it can handle single-leg work.

Weeks 1–6: the rehab that prevents the next one

Ligaments do more than hold bones together — they're packed with position sensors. A sprain damages the wiring as well as the rope, which is why balance retraining is the core of ankle rehab:

1. Range: ankle circles, calf stretches — restore full movement, especially bringing the shin over the foot (my calf mobility drills double up here).
2. Strength: resistance-band work in all four directions; calf raises building to single-leg.
3. Balance: single-leg stance — 30 seconds eyes open, then eyes closed, then on a cushion. Daily. This is the evidence-backed bit everyone skips.
4. Power and agility: hopping, direction changes, sport drills — before full return, not instead of it.

Ankle sprain physiotherapy: the phase-by-phase rehabilitation protocol

Patients often ask what ankle sprain physiotherapy actually involves — whether they need to be seen in clinic, or whether it's something they can run themselves. The honest answer: for most grade 1–2 sprains, the protocol below is exactly what I'd progress you through in clinic, and a motivated person can self-manage it. A physiotherapist earns their fee when progress stalls, when the grading is uncertain, or when you need to hit a return-to-sport date.

Ankle sprain rehabilitation runs in four overlapping phases. You move to the next phase when you meet the goals, not when the calendar says so — and a grade 3 sprain stretches every timescale below, sometimes doubling it.

The exit test I use before clearing anyone for sport: 30 seconds of single-leg balance with eyes closed, ten single-leg hops matching the other side for height and comfort, and no apprehension cutting side to side. Fail any of those and phase 4 isn't finished — however long ago the sprain was.

Returning to running specifically: pass the exit test on flat, even ground before you touch a trail — uneven surfaces demand exactly the ankle-position sense a fresh sprain hasn't rebuilt yet. Start with short, easy runs and build distance before pace, and expect the ankle to feel more cautious than the rest of you for a few weeks. For the general framework on reloading after any running injury, see Running's running injury prevention exercises.

Getting a sprained ankle treated in the UK

Where to actually take an ankle injury depends on the first 24 hours. If you can't take four steps, there's tenderness directly on the bone, or the foot looks wrong, that's urgent care or A&E for an X-ray — the NHS guidance is clear on those thresholds. Everything short of that starts with the self-care above, because the protocol genuinely is the treatment for most grade 1–2 sprains.

If the ankle isn't clearly improving after two weeks, or it's still swollen, unstable or painful to walk on at four to six, get it assessed. The NHS route is your GP or, in many areas, self-referral to NHS physiotherapy — search your local trust's website for "physio self-referral" (my guide to seeing a physiotherapist in the UK walks through every route and what it costs). Waiting lists vary by area, which is why private ankle ligament sprain treatment is a common middle path: a private physiotherapist typically charges £40–70 per session, and most sprains need only a few sessions spread across the rehab phases — the daily balance and strength work between appointments is where recovery actually happens, whoever supervises it.

What good ankle treatment looks like in either system: an assessment that grades the sprain and rules out the lookalikes, a phased plan like the table above with clear exit tests, and a return-to-sport date based on what your ankle can do rather than how long it's been. Be more sceptical of care that is mostly machines, ultrasound or endless passive treatment with no progressive loading — that pattern predicts the recurring sprain.

Managing a sprained ankle at home: care, remedies and honest advice

Most ankle sprain management happens at home, in the weeks after the first-aid phase — and this is where I field the most questions in clinic. The advice that actually matters day to day:

• Evening swelling is normal for weeks. An ankle that swells after a long day but is better each morning is healing on schedule. Swelling that trends up week on week isn't — get it looked at.
• Use support tactically, not permanently. A tubular bandage or lace-up brace during long days on your feet is sensible ankle sprain care in the first weeks; wearing it on the sofa teaches you nothing and the ankle less.
• Footwear counts as treatment. Supportive lace-up shoes or trainers beat sliders, flats and bare feet while the ligament is remodelling — the same logic as bracing, built into your day.
• Heat is fine after the first few days — a warm soak before your exercises can make the stiffness easier to work through. It's a comfort tool, not a cure.

On remedies: pharmacy shelves offer plenty for ankle sprains, and most of it is comfort rather than repair. Ice, compression and simple analgesia have a job in the early phase; anti-inflammatory gels can take an edge off; arnica, magnesium sprays and "recovery" supplements have no meaningful evidence for ligament healing. None of them are harmful in normal use — the harm is spending your effort there instead of on the strength and balance work above, which is the only remedy that changes the ankle you'll have next year.

Common misconceptions I see in my patients

• "It's just a sprain." Without rehab, roughly a third of people develop chronic ankle instability — recurrent giving-way that outlasts the original injury by years.
• "If I can walk on it, it's not serious." Walking rules out some things, not all. Pain directly on the bone or a sense of instability still deserves assessment.
• "Strapping forever protects it." Taping helps during return to sport; long-term, trained balance and strength are what actually protect it — the theme of my injury prevention guide.

FAQ: ankle sprain treatment

How long does a sprained ankle take to heal?

Mild sprains: 1–3 weeks. Moderate: 4–6 weeks. Complete ligament tears: 8–12 weeks or more. Balance and confidence often need deliberate work beyond all of those.

Should I walk on a sprained ankle or rest it?

Walk on it as pain allows, early. Evidence consistently favours early weight-bearing and movement over strict rest for ligament sprains — protect it, don't imprison it.

Why does my ankle still hurt months after a sprain?

Commonest reasons: incomplete rehab (weak, poorly balanced ankle), or a missed additional injury. Persistent pain or giving-way at 8+ weeks deserves a professional assessment rather than more waiting.
