What is severe ankle sprain?

A severe ankle sprain is a complete tear of one of the ligaments that connect the bones in the foot, ankle, and lower leg. Sudden force, twisting of the ankle, or a dislocated or broken bone can cause the ligament to tear. A tear can cause swelling, pain, bruising, and loss of strength and movement. Your ankle may feel wobbly.

The most commonly torn ligaments are the ones on the outside of the ankle that connect your outer leg bone (fibula) to the bones of your foot.

A severe ankle sprain can first be treated with:

• The RICE method. It stands for: Rest. Ice. Compression, or wrapping the injured area with an elastic bandage. Elevation, or propping up the injured area.
• A splint, brace, or crutches. These devices can help support and protect your ankle and allow the ligament to heal.
• Over-the-counter pain medicines, such as acetaminophen or NSAIDs.
• Avoiding activity that may cause pain or more damage to the ligament.

After the initial pain and swelling are reduced, your doctor may suggest physical therapy to help you get back full motion and strength in your ankle.

It may take 6 to 12 weeks or more for your ankle to heal.

In some cases, surgery and physical therapy may be needed to treat a completely torn ligament.
