First Aid and Care for a Sprained Ankle

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

An ankle sprain happens when the ligaments supporting the ankle joint stretch beyond their limits or tear during an unnatural twist or turn. Immediate first-aid treatment helps reduce inflammation, relieve pain, and prevent chronic instability. While mild sprains heal with home care, severe ligament tears or bone fractures require formal medical diagnosis.

Quick Summary

Treat an acute ankle sprain immediately using rest, ice, compression, and elevation (R.I.C.E.), and seek medical evaluation if you cannot bear weight.

Step-by-Step Guide

1

Rest and protect the joint

Immediately stop the activity that caused the injury and sit down in a safe location. Avoid bearing weight on the affected foot to protect the compromised ligaments from further tearing. If you need to move, use crutches or rely on support from another person.

Important: Do not attempt to 'walk off' an ankle injury, as putting weight on unstable ligaments can worsen a partial tear or displace an undetected fracture.

2

Apply cold therapy

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

Important: Never apply ice directly to bare skin, as prolonged direct contact can cause frostbite and skin damage.

3

Wrap with an elastic compression bandage

Wrap an elastic bandage (such as an ACE wrap) firmly around the foot and ankle, starting at the toes and spiraling upward toward the mid-calf. Ensure each turn overlaps the previous one by about half. The bandage should feel snug and supportive without cutting off circulation.

Important: If your toes feel cold, become pale or blue, or start tingling, the wrap is too tight. Remove it immediately and rewrap it more loosely.

4

Elevate the ankle above the heart

Lie down or recline and prop the injured leg on pillows so that the ankle sits above the level of your heart. Maintaining this position as much as possible for the first 48 hours uses gravity to drain excess fluid and significantly reduces throbbing and edema.

5

Manage pain and inflammation

Consider taking over-the-counter pain medications if medically appropriate for you. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen can relieve pain and reduce joint inflammation. Alternatively, acetaminophen helps manage pain without affecting inflammation.

6

Assess for signs of a fracture

Check for key warning signs that indicate a possible broken bone rather than a simple ligament sprain. Clinicians use the Ottawa Ankle Rules to evaluate fractures, checking for localized bone tenderness on the lower 6 centimeters of the outer or inner ankle bones and the ability to bear weight.

Important: Seek prompt medical attention or an X-ray if you cannot take four steps independently, felt or heard a distinct 'pop', notice obvious deformity, or have severe localized pain directly on the ankle bones.

Frequently Asked Questions

How can I tell the difference between a sprain and a fracture?
Both injuries cause pain, swelling, and bruising. However, a fracture is more likely if you heard a loud snap, have visible bone deformity, feel sharp pain when pressing directly on the bony prominences of the ankle, or are entirely unable to take four steps immediately after the injury.
Should I apply heat or ice to a newly sprained ankle?
Use ice during the first 48 to 72 hours. Cold therapy constricts blood vessels and limits swelling and internal bleeding. Avoid heat during this initial phase, as heat dilates vessels and can increase inflammation and swelling.
How long does it take for a sprained ankle to heal?
Recovery depends on severity. Mild (Grade I) sprains often feel significantly better within 1 to 3 weeks. Moderate (Grade II) sprains with partial tears typically take 4 to 6 weeks, while severe (Grade III) complete tears may take 8 to 12 weeks or longer and often require physical therapy.
When can I start walking or exercising again?
You can begin gentle weight-bearing as tolerated once sharp pain subsides, usually within a few days for mild sprains. Support the ankle with a brace or wrap during early walking. Avoid high-impact sports, running, or cutting movements until you regain full range of motion, strength, and balance without pain.
