First Aid and Care 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. Prompt first aid controls swelling, alleviates pain, and prevents further joint damage. Proper acute management provides the foundation for safe, long-term ligament healing.

Quick Summary

Immediately rest, ice, compress, and elevate (PRICE) the joint, and seek medical attention if you cannot bear weight or notice visible deformity.

Step-by-Step Guide

1

Check for Signs of a Fracture

Examine the ankle for visible bone deformity, severe bruising, or pinpoint bone tenderness directly over the bony protrusions (malleoli). Attempt to determine if the person can bear any weight on the foot. The Ottawa Ankle Rules indicate that an inability to take four steps or direct tenderness over the back edges of the ankle bones warrants medical evaluation for a possible break.

Important: Seek immediate emergency medical care if the ankle appears deformed, the foot is pale or cold, or there is severe numbness.

2

Rest and Protect the Joint

Stop the activity immediately and avoid putting weight on the injured foot. Continuing to walk on a fresh ligament sprain can widen tears and prolong recovery time. Use crutches, a walking boot, or lean on a helper if movement is strictly necessary.

3

Apply Cold Therapy

Place an ice pack or a bag of frozen vegetables wrapped in a thin towel onto the swollen area for 15 to 20 minutes at a time. Repeat this every 2 to 3 hours during waking hours for the first 48 hours. Cold constricts local blood vessels, which reduces internal bleeding, fluid accumulation, and throbbing pain.

Important: Never apply ice directly to bare skin, as this can cause localized frostbite or tissue damage.

4

Wrap with an Elastic Compression Bandage

Wrap the ankle using an elastic bandage (such as an ACE wrap) to stabilize the joint and minimize swelling. Begin wrapping at the base of the toes and spiral upward toward the lower calf, overlapping each turn by roughly half. The wrap should feel snug and supportive, but not uncomfortably tight.

Important: Loosen the bandage immediately if your toes become numb, tingle, turn pale or blue, or feel cold.

5

Elevate the Ankle Above Heart Level

Lie down and prop the injured leg on pillows so that the ankle sits above the level of your heart. Elevation uses gravity to drain excess fluid and inflammatory mediators away from the ankle joint back into circulation. Maintain this elevated position as frequently as possible throughout the first 48 hours.

6

Manage Pain and Inflammation

Over-the-counter pain medications like acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, can help control acute pain. Follow the package instructions carefully and use the lowest effective dose. Consult a physician or pharmacist prior to use if you have kidney disease, high blood pressure, or a history of stomach ulcers.

7

Begin Gentle Range-of-Motion Exercises

Once the initial severe throbbing and swelling begin to subside (typically after 48 to 72 hours), start gentle, non-weight-bearing motion. Trace the letters of the alphabet in the air with your big toe or perform slow ankle circles within a pain-free range. Early, controlled movement prevents joint stiffness and encourages functional ligament remodeling.

Frequently Asked Questions

How can I tell if my ankle is sprained or broken?
While an X-ray is required for a definitive diagnosis, a fracture is more likely if you cannot bear any weight to walk four steps, have severe tenderness directly over the bony points of the ankle, or notice visible bone deformity. Sprains generally cause soft tissue tenderness directly over the ligaments rather than the bone.
Should I apply heat or ice to an ankle sprain?
Use ice during the first 48 to 72 hours to reduce acute inflammation and swelling. Avoid applying heat in the acute phase, because heat dilates blood vessels and increases swelling; heat may be introduced later to relax stiff muscles once swelling has subsided.
How long does a sprained ankle take to heal?
Mild (Grade I) sprains typically heal within 1 to 3 weeks with proper rest and rehabilitation. Moderate (Grade II) sprains usually take 3 to 6 weeks, while severe (Grade III) tears can take several months and may require formal physical therapy or immobilization.
Is it safe to walk on a sprained ankle?
You should not walk if it causes significant pain or causes you to limp heavily. Once acute pain subsides and you can place weight down comfortably, gradual weight-bearing with supportive shoes or an ankle brace is beneficial for recovery.
