What is it?

An ankle sprain — often called a “rolled ankle” — is one of the most common sports injuries.

• Most sprains happen when the foot rolls inward, stretching or tearing the ligaments on the outside of the ankle. Ligaments are the strong bands of tissue that connect bones and keep joints stable.
• Typical scenarios: landing on someone’s foot in basketball, stepping into a pothole while running, or missing a step on the stairs.

Sprains are graded by severity:

• Grade I (mild): the ligament is stretched but not torn. Mild swelling and pain; you can usually still walk.
• Grade II (moderate): the ligament is partially torn. Clear swelling and bruising; walking hurts.
• Grade III (severe): the ligament is completely torn. Major swelling, an unstable joint, and often you can’t put weight on the foot.

Common symptoms

• Pain on the outside of the ankle, especially just below and in front of the outer ankle bone
• Swelling, usually within a few hours of the injury
• Bruising, which may appear a day or two later and can spread toward the toes
• Pain when standing or walking on the foot
• A loose or “giving way” feeling in the joint (with more severe sprains)
• Sometimes a “pop” felt or heard at the moment of injury

Why does it happen? (Risk factors)

• A previous ankle sprain — the single biggest risk factor. An old injury leaves the ligaments looser and the ankle’s position sense weaker, making the next sprain more likely.
• Poor balance and proprioception. Proprioception is your body’s ability to know where a joint is without looking. When it’s impaired, the ankle can’t react in time.
• Weak calf and ankle muscles — muscles are the second line of defense after ligaments.
• Sport type: jumping, landing, and cutting sports (basketball, volleyball, badminton, soccer) carry higher risk.
• Surfaces and gear: uneven ground, poorly fitting shoes.
• Inadequate warm-up or playing while fatigued.

How is it diagnosed?

• Your doctor will ask how the injury happened, then examine the ankle — pressing to find tender spots and gently moving the joint to test ligament stability.
• Not every sprain needs an X-ray. Doctors use the Ottawa ankle rules to decide. In plain terms, an X-ray to rule out a fracture is mainly needed if:
  • You cannot take four steps on the foot, both right after the injury and at the clinic
  • Pressing on the bony tips of the inner or outer ankle is clearly painful
  • Pressing on certain foot bones (the base of the fifth metatarsal or the navicular) is painful
• If a severe ligament tear is suspected, or recovery is slower than expected, your doctor may order an ultrasound or MRI to look at the soft tissues.

Treatment and self-care

The vast majority of ankle sprains do not need surgery — good rehabilitation gets you back.

First few days: PEACE

• P — Protect: avoid activities that clearly worsen pain for the first few days, but don’t shut down completely.
• E — Elevate: raise the foot above heart level to reduce swelling.
• A — Avoid anti-inflammatories (and excessive ice): inflammation is part of normal healing. Long courses of anti-inflammatory drugs and constant icing aren’t recommended. Brief icing for pain relief is fine, but not required.
• C — Compress: an elastic bandage or brace helps limit swelling.
• E — Educate: understanding the recovery process helps you avoid unnecessary scans and over-treatment.

Once pain settles: LOVE

• L — Load: start walking and moving the ankle early, as long as pain stays manageable. Gradual loading signals the tissue to heal stronger.
• O — Optimism: mindset genuinely affects recovery, and most people recover fully.
• V — Vascularisation: pain-free cardio (like cycling) boosts blood flow to the healing tissue.
• E — Exercise: strength, mobility, and balance training are the key to preventing the next sprain.

Why isn’t RICE (Rest, Ice, Compression, Elevation) emphasized anymore?

• Research showed that prolonged rest actually slows recovery — healing tissue needs gradual loading to remodel well.
• Too much icing may delay tissue repair, so ice is now suggested only briefly, for pain relief.
• The thinking has shifted from “rest and protect” to “protected early movement and progressive loading.”

Other key points

• For most grades, functional support works better than rigid immobilization like a cast — and a semi-rigid brace (lace-up or stirrup style) is preferred over elastic bandages or taping, as it gives steadier support and is more cost-effective. It protects the ankle while letting you move, which speeds recovery. Only a minority of severe (Grade III) injuries need a short period of immobilization (about 10 days or less).
• Balance and proprioception training (single-leg standing, progressing to unstable surfaces) substantially lowers the risk of re-sprain and of developing chronic ankle instability. It’s the most important part of rehab.
• Rough recovery timelines: Grade I about 1–3 weeks, Grade II about 3–6 weeks, Grade III often 2–3 months or more. Everyone is different.

When to seek medical care — red flags

See a doctor promptly if any of the following apply:

• You cannot put weight on the foot or take four steps after the injury
• Pressing on the ankle or foot bones (inner/outer ankle bone, base of the fifth metatarsal, navicular) is clearly painful — this could mean a fracture
• The ankle looks deformed or sits at an odd angle
• The foot or toes feel numb or tingly, or the skin turns pale or bluish — possible nerve or blood-vessel involvement
• Pain sits at the front of the ankle, between the two shin bones, or hurts when the lower leg is rotated outward — possible high ankle (syndesmotic) sprain, which heals more slowly and is managed differently
• Pain and swelling are getting worse instead of better after a few weeks

Frequently asked questions

Q: When can I return to sport? Roughly 1–3 weeks for mild sprains, 3–6 weeks for moderate, and 2–3 months for severe ones. More important than the calendar are functional milestones: you can walk, jog, and hop on one leg without pain, and single-leg balance and strength are close to the other side — then build back through practice before competition. Returning too early is the main cause of re-sprain.

Q: Why does my ankle keep spraining? If the first sprain isn’t fully rehabilitated, loose ligaments plus impaired proprioception can turn into “chronic ankle instability.” The fix isn’t more rest — it’s consistent balance and strength training, with an ankle brace during sport (for up to 12 months after the injury) to lower the risk of re-spraining. Recurrent sprains deserve a proper medical assessment.

Q: Do I need surgery? Almost certainly not. Even for Grade III sprains (a completely torn ligament), studies show that rehabilitation first usually works as well as surgery. Surgery is reserved for the few ankles that remain clearly unstable after proper rehab.

Q: My ankle is still swollen — is it okay to walk? Yes, as long as pain is tolerable and none of the red flags above apply. Early protected walking (for example, with a brace) actually helps recovery. Use pain as your traffic light: mild discomfort during activity is acceptable; back off if pain clearly worsens.
