A sprain is stretching or tearing of ligaments, which connect adjacent bones in a joint and provides stability to the joint. An ankle sprain is a common injury and occurs when you fall or suddenly twist the ankle joint or when you land your foot in an awkward position after a jump. It most commonly occurs when you participate in sports or when you jump or run on a surface that is irregular. Ankle sprains can cause pain, swelling, tenderness, bruising, and stiffness, numbness in the toes, and inability to walk or bear weight on the ankle.
The diagnosis of an ankle sprain is usually made by asking the history of injury and physical examination of the ankle. X-ray of your ankle may be needed to confirm if a fracture is present.
The most common treatment recommended for ankle sprains is rest, ice, compression and elevation (RICE).
- Rest: You should not move or use the injured part to help to reduce pain and prevent further damage. Crutches may be used that help in walking
- Ice: An ice-pack should be applied over the injured area up to 3 days after the injury. You can use a cold pack or crushed ice wrapped in a towel. Ice packs help to reduce swelling and relieve pain. Never place ice directly on the skin
- Compression: Compression of the injured area helps to reduce swelling and bruising. This is usually accomplished by using an elastic wrap for few days to weeks after the injury
- Elevation: Place the injured part above heart level to reduce swelling. Elevation of an injured leg can be done for about 2 to 3 hours a day
The doctor may also use a brace or splint to reduce motion of the ankle. Anti-inflammatory pain medications may be prescribed to help reduce the pain and control inflammation.
You may need to use an ankle brace or wrap to support and protect your ankle during sports activities. Avoid pivoting and twisting movements for 2 to 3 weeks.
To prevent further sprains or re-injury you may need to wear a semi-rigid ankle brace during exercise, special wraps, and high-top tennis shoes. A program of ankle exercises will also help to prevent re-injury by making the ankles strong and flexible.
