First Aid for a Sprained Ankle

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

An ankle sprain occurs when the ligaments supporting the joint are stretched or torn, commonly after twisting or rolling the foot inward. Prompt first aid reduces swelling, controls pain, and speeds recovery while preventing long-term instability. Knowing when to immobilize the joint and when to seek medical evaluation is critical for proper healing.

Quick Summary

Immediately protect and rest the ankle, apply cold therapy and compression, elevate the joint above heart level, and seek medical care if you cannot bear weight.

Step-by-Step Guide

1

Stop Activity and Check for Red Flags

Immediately stop bearing weight on the affected leg and sit down safely. Inspect the ankle for visible bone deformity, severe open wounds, or rapid localized bruising directly over the bony points. Assess whether the person can stand or take four steps without unbearable pain.

Important: Seek emergency medical care immediately if the joint appears visibly deformed, if the foot is cold, pale, or completely numb, or if the injured person cannot take four steps.

2

Protect and Rest the Joint

Avoid walking or putting pressure on the injured foot to prevent further stretching or tearing of compromised ligaments. Use crutches, a walking boot, or support from another person if movement is necessary. Keep the ankle immobilized in a neutral position.

3

Apply Cold Therapy

Apply an ice pack or a bag of frozen vegetables wrapped in a thin towel to the swollen area for 15 to 20 minutes at a time. Repeat this every 2 to 3 hours during the first 48 hours following the injury to constrict blood vessels and limit edema.

Important: Never place ice directly against the skin, as prolonged direct contact can cause frostbite or cold-induced tissue necrosis.

4

Apply a Compression Bandage

Wrap the foot and ankle snugly with an elastic compression bandage (such as an ACE wrap) to minimize interstitial swelling. Begin at the base of the toes and wrap upward past the ankle toward the calf, overlapping each layer by half. Ensure the wrap is firm but comfortable.

Important: Loosen the bandage immediately if you experience throbbing, increased pain, numbness, tingling, or if your toes turn pale or blue.

5

Elevate the Ankle Above the Heart

Prop the injured foot up on pillows while resting, ensuring the ankle is elevated above the level of the heart whenever possible. Elevation utilizes gravity to facilitate venous and lymphatic return, dramatically reducing throbbing and swelling. Maintain this position for as much of the first 48 hours as possible.

6

Manage Pain and Discomfort

Over-the-counter pain medications like acetaminophen can help control mild-to-moderate discomfort. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen may reduce swelling and pain, but should be used following product guidelines and clinician advice.

Important: Consult a healthcare provider before taking NSAIDs if you have a history of stomach ulcers, kidney disease, or cardiovascular disorders.

7

Begin Gentle Range-of-Motion Exercises

Once severe swelling and acute pain begin to settle (usually after 48 to 72 hours), begin gentle non-weight-bearing mobility. Try tracing the letters of the alphabet in the air with your big toe or performing gentle seated ankle circles. Stop immediately if exercises cause sharp or worsening pain.

Frequently Asked Questions

How do I know if my ankle is sprained or broken?
While both cause pain and swelling, a fracture often presents with pinpoint bone tenderness along the lower edges of the fibula or tibia, visible deformity, or an inability to take four steps both immediately after the injury and in an examination. An X-ray is required to definitively distinguish between a severe sprain and a bone fracture.
How long does a sprained ankle take to heal?
A mild (Grade 1) sprain typically heals within 1 to 3 weeks with proper rest. Moderate (Grade 2) sprains involving partial tears generally take 4 to 6 weeks, while severe (Grade 3) complete ligament tears can take 3 to 6 months and often require formal physical therapy or orthopedic management.
Should I apply heat or ice to a newly sprained ankle?
Always apply cold therapy, not heat, for the first 48 to 72 hours. Cold reduces blood flow and decreases tissue swelling, whereas applying heat too early increases vascular dilation and can worsen inflammation and edema.
When can I start walking normally again?
You can begin progressive weight-bearing as tolerated once you can stand flat-footed without sharp pain or significant limping. Wearing a semi-rigid supportive ankle brace can protect the healing ligaments as you gradually resume routine walking.
