First Aid and Care for a Sprained Ankle

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

An ankle sprain occurs when the tough ligaments supporting the joint are stretched or torn beyond their normal range. Immediate first aid using protection, rest, ice, compression, and elevation helps minimize soft tissue swelling and pain. Following proper recovery steps reduces the risk of chronic instability and long-term joint complications.

Quick Summary

Treat an acute ankle sprain promptly using the R.I.C.E. protocol to control swelling and pain, and seek medical evaluation if you cannot bear weight.

Step-by-Step Guide

1

Stop Activity and Assess the Injury

Cease physical activity immediately and sit down in a safe, comfortable spot. Inspect the ankle for visible bone deformity, severe skin discoloration, or rapid swelling. Gently assess whether the person can bear any weight on the foot.

Important: Do not attempt to walk on an ankle with visible deformity, severe bone pain, or total inability to bear weight, as this may indicate a bone fracture.

2

Rest and Protect the Joint

Keep weight completely off the affected ankle for the first 24 to 48 hours to prevent further ligament trauma. Use crutches, a cane, or support from others if moving is unavoidable. A temporary splint or supportive brace can provide structural stability.

3

Apply Cold Therapy

Apply an ice pack or a bag of frozen vegetables wrapped in a thin towel to the injured area for 15 to 20 minutes every 2 to 3 hours during the initial 48 hours. Cold constricts local blood vessels, decreasing swelling, tissue bleeding, and localized pain.

Important: Never apply ice directly against bare skin, as prolonged direct exposure can cause frostbite or nerve damage.

4

Apply an Elastic Compression Wrap

Wrap the ankle using an elastic bandage, starting at the base of the toes and spiraling upward toward the mid-calf. Ensure the bandage is snug enough to provide firm support and contain swelling, overlapping each turn by half its width.

Important: Loosen the bandage immediately if the toes become pale, blue, cold to the touch, numb, or start tingling.

5

Elevate the Ankle Above Heart Level

Prop the leg on pillows or cushions so the injured ankle rests at or above the level of the heart whenever sitting or lying down. Elevation uses gravity to drain pooled fluids away from the joint, significantly reducing throbbing and edema.

6

Manage Discomfort with Over-the-Counter Medication

Take over-the-counter pain relievers such as acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen to reduce pain and inflammation. Follow package dosing directions carefully and consult a healthcare provider if you have preexisting health conditions.

Important: Avoid NSAIDs if you have active stomach ulcers, renal disease, or bleeding disorders unless approved by a physician.

7

Begin Gentle Range-of-Motion Exercises

After 48 to 72 hours, once severe swelling and acute pain stabilize, begin gentle non-weight-bearing mobility exercises. Trace the letters of the alphabet in the air with your big toe or perform gentle ankle circles to preserve joint mobility and prevent excessive stiffness.

Important: Stop immediately if movement causes sharp or worsening pain.

Frequently Asked Questions

How can I tell the difference between a sprain and a fracture?
Both injuries present with pain, swelling, and bruising. However, a fracture is more likely if you heard a loud crack, have intense tenderness directly over the bony protrusions (malleoli), have visible joint deformity, or cannot take four steps immediately after the injury. An X-ray is required to reliably diagnose a break.
Should I apply heat or ice to an ankle sprain?
Use ice during the first 48 to 72 hours to reduce inflammation and blood flow to the damaged tissue. Heat increases circulation and can worsen swelling if used too early. Reserve heat therapy for later stages of recovery to loosen tight muscles before rehabilitation exercises.
How long does a sprained ankle take to heal?
Mild sprains (Grade I) typically heal within 1 to 3 weeks with conservative home care. Moderate sprains (Grade II) with partial ligament tears generally take 4 to 6 weeks, while severe sprains (Grade III) involving complete tears can take 8 to 12 weeks or longer and often require formal physical therapy.
When should I see a doctor for an ankle injury?
Seek medical attention if you cannot bear weight on the foot, experience persistent numbness or tingling, observe severe swelling or deformity, or notice no improvement after 3 to 5 days of home care.
