First Aid and Care for a Sprained Ankle

Published: October 19, 2026Updated: October 19, 2026

An ankle sprain happens when the tough bands of tissue holding the joint together stretch or tear, usually after an awkward twist or roll. Starting prompt first aid reduces painful swelling, stabilizes the joint, and prevents long-term instability. Learn how to safely care for the injury at home and recognize when professional evaluation is necessary.

Quick Summary

Rest, ice, compress, and elevate your injured ankle immediately, and seek medical care if you cannot bear weight or have severe pinpoint bone tenderness.

Step-by-Step Guide

1

Assess the joint for signs of a fracture

Check whether the person can put weight on the foot and take four steps, and gently check for pinpoint tenderness over the bony bumps on either side of the ankle. Note any visible deformity, numbness, coldness in the toes, or rapid, severe bruising. If the ankle appears crooked or bearing any weight is impossible, immobilize the joint and seek urgent medical evaluation.

Important: Seek immediate medical care if the ankle is visibly deformed, unable to bear any weight, or completely numb, as these symptoms indicate a potential fracture or severe ligament tear.

2

Rest and protect the ankle

Stop activity immediately and keep all weight off the affected foot. Continuing to walk on an acute ligament sprain can worsen the tear and increase bleeding in the surrounding tissues. If walking is essential, use crutches, a walking boot, or a supportive ankle brace to protect the joint.

3

Apply cold therapy

Place an ice pack or a bag of frozen vegetables wrapped in a thin cloth onto the swollen area for 15 to 20 minutes at a time. Repeat this application every 2 to 3 hours during the first 48 hours following the injury. Cold therapy narrows blood vessels, which curbs fluid accumulation, reduces bruising, and numbs sharp pain.

Important: Never place ice directly against bare skin, as prolonged contact can cause frostbite and tissue damage.

4

Compress the joint with an elastic bandage

Wrap the foot and ankle using an elastic compression bandage to stabilize the joint and minimize fluid buildup. Start near the toes and wrap upward past the ankle joint toward the calf using overlapping figure-eight turns with moderate tension. The wrap should feel snug and secure but not painfully tight.

Important: Loosen the bandage immediately if your toes become numb, cold, pale, tingly, or increasingly painful.

5

Elevate the ankle above the heart

Prop the injured foot up on pillows so that it rests above the level of your heart whenever you are sitting or lying down. Gravitational drainage helps excess fluid flow away from the ankle joint back into circulation. Maintain this elevated position as frequently as possible during the first 48 to 72 hours to control throbbing and edema.

6

Manage pain and inflammation

Over-the-counter medications such as ibuprofen or naproxen can relieve pain and reduce inflammatory swelling. Acetaminophen is an effective alternative for pain control if you cannot take nonsteroidal anti-inflammatory drugs. Always use the lowest effective dose according to the package directions or your physician's guidance.

7

Begin gentle early mobilization

After 48 to 72 hours, once acute throbbing subsides, start gentle range-of-motion exercises such as tracing the alphabet in the air with your big toe or performing small ankle circles. Gradual, pain-free movement prevents joint stiffness and improves blood flow to aid ligament healing. Avoid any movement that provokes sharp or worsening pain.

Frequently Asked Questions

How can I tell if my ankle is sprained or broken?
Both injuries cause swelling and bruising, but a broken bone often causes intense point tenderness directly over the bony protrusions (malleoli), visible deformity, or an absolute inability to bear weight for four steps. An X-ray is required to definitively distinguish between a severe sprain and a fracture.
Should I use heat or ice for an ankle sprain?
Use ice for the first 48 to 72 hours to reduce inflammation and swelling. Applying heat too early increases blood circulation to the injured area, which worsens swelling and throbbing. Heat is only useful later during recovery to loosen stiff, recovering muscles.
How long does a sprained ankle take to heal?
A mild (Grade 1) sprain typically recovers within 1 to 3 weeks with conservative home care. Moderate (Grade 2) sprains often require 4 to 6 weeks, while severe (Grade 3) complete tears can take several months and may require structured physical therapy or immobilization.
When should I see a doctor for a sprain?
Consult a healthcare professional if you cannot take four steps on the foot, if the ankle is visibly deformed, if pain and swelling do not improve after 3 to 5 days, or if you feel numbness or pins-and-needles in your foot.
