One minute you’re jogging, playing five-a-side or just missing a kerb — the next, your ankle is swelling like a balloon and you’re hopping on one foot. Knowing how to treat a sprained ankle at home properly makes the difference between being back on your feet in a week and limping for a month. Most sprains are mild and heal perfectly well with home care, as long as you don’t do the classic British thing of “walking it off” too soon.

A sprain means you’ve stretched or torn the ligaments — the tough bands holding your ankle joint together. It usually happens when the foot rolls inward. The good news: with the right early care, most mild-to-moderate sprains recover fully at home. Here’s the playbook.

First 48 hours: protect and reduce swelling

The old RICE advice has been updated slightly — the current thinking is PEACE & LOVE (yes, really), but for practical purposes, here’s what to do in the first two days:

  • Protect: stop the activity immediately. Don’t test it by walking on it “to see”. Avoid anything that causes pain for the first 1–3 days.
  • Raise it: keep the ankle raised above heart level as much as possible — propped on pillows while you rest. This is the single most effective swelling-reducer.
  • Ice: 15–20 minutes every 2–3 hours, wrapped in a tea towel (never directly on skin). A bag of frozen peas moulds to the ankle perfectly.
  • Compress: a snug elastic bandage from toes upward reduces swelling — firm but not numbness-tight. Remove it at night.
  • Avoid anti-inflammatories in the first 48 hours? This is debated — some physios now suggest avoiding ibuprofen initially since inflammation is part of healing. Paracetamol for pain is uncontroversial. The NHS guidance on sprains and strains remains the best reference for current advice.

Avoid heat, alcohol, running and massage in the first 72 hours — they all increase bleeding and swelling. (Physios memorise this as “HARM”.)

How to treat a sprained ankle at home: days 3–14

Once the worst swelling settles, the goal shifts from protection to gentle rehabilitation. This is where most people go wrong — either by resting completely for weeks (which weakens the ankle) or by doing too much too soon.

  1. Start gentle movement early. As soon as you can bear some weight, begin ankle circles and “alphabet” exercises (trace the alphabet with your big toe). Pain-free movement prevents stiffness.
  2. Gradually reload. Walk normally as soon as limping stops — limping creates bad patterns. Use a single crutch or stick on the opposite side if needed for a few days.
  3. Rebuild strength and balance. This is the bit everyone skips, and it’s why ankles get re-sprained. Calf raises, resistance-band pushes in all directions, and single-leg balance stands (30 seconds, eyes open, then eyes closed) retrain the stabilising muscles. Do these daily for at least two weeks after pain resolves.
  4. Consider support. An elastic ankle support or lace-up brace (£8–£15 from Boots or Amazon) helps confidence when returning to activity, but don’t become dependent on it long-term.

Having a stocked home first aid kit means the bandage, ice pack and painkillers are to hand when it happens — worth sorting before you need it.

How long until I’m better?

Grade I (mild stretch): 1–2 weeks. Grade II (partial tear, significant swelling and bruising): 3–6 weeks. Grade III (complete tear, very unstable): potentially months and needs medical assessment. Most home-treated sprains are Grade I–II. If you’re not clearly improving after a week, or can’t bear weight after a few days, get it checked.

Red flags: when home treatment isn’t enough

See a GP, urgent care or A&E if:

  • You can’t bear any weight on it after 2–3 days, or heard a “pop” at the time of injury
  • The ankle looks deformed or the pain is severe and unrelenting
  • Numbness, pale or cold foot, or pain above the ankle (possible fracture — the Ottawa ankle rules clinicians use exist precisely because breaks hide among sprains)
  • Swelling hasn’t improved after a week of proper home care
  • It’s a repeat sprain of the same ankle — chronic instability needs physio assessment

When you’re ready to move again, ease back in sensibly — our guide to home workouts includes plenty of ankle-friendly options while you rebuild.

Ankle sprain recovery: the week-by-week timeline

Knowing what’s normal at each stage stops you either panicking or rushing back too soon. Timelines vary with severity, but this is the typical pattern for a mild-to-moderate sprain treated at home.

Days 1–3: protect and calm. This is the PEACE phase — protection, raising it, compression, and avoiding anti-inflammatories in the first day or two (they can interfere with the early healing response). Expect swelling, bruising and pain on weight-bearing. Crutches or at least a careful limp are sensible; “walking it off” on day one is how mild sprains become chronic ones.

Days 4–7: gentle movement returns. The LOVE phase begins — light movement as pain allows. Ankle circles, tracing the alphabet with your toes, gentle calf stretches. The goal is to restore range of motion, not to test strength. Swelling should be clearly reducing; if it’s not, or bruising is spreading dramatically, get it checked.

Week 2: rebuild. Balance work starts now — standing on the injured foot while brushing your teeth is the classic rehab exercise because it fits into life. Resistance band exercises (pushing the foot against the band in all four directions), heel raises, and short walks on even ground. Mild discomfort during exercise is fine; sharp pain or swelling that worsens afterwards means you overdid it.

Weeks 3–4: return to normal. Most mild sprains feel 80–90% by now. The mistake is stopping rehab here — the last 10% (full balance, confidence on uneven ground, strength symmetry) is what prevents the sprain-sprain-sprain cycle that plagues people who “recovered” too fast. Keep the balance exercises going for another fortnight.

See a GP or minor injuries unit if: you can’t bear weight at all after 24 hours, there’s numbness, the ankle looks deformed, or it’s not clearly improving after a week. Those are fracture/dislocation signs, not sprain behaviour.

Your takeaway: respect the first 48 hours, rehab the next two weeks

To treat a sprained ankle at home: protect and raise it immediately, ice regularly, compress snugly, then — crucially — rehabilitate with movement, strength and balance exercises rather than prolonged rest. Get medical help for severe pain, deformity, numbness or no improvement within a week. Treat it right and your ankle will be stronger than the one you injured.
