Ankle pain

Ankle pain involves any discomfort in one or both ankles.

Alternative Names

Pain - ankle; Sprain - ankle; Ankle sprain

Common Causes

Ankle pain is often due to an ankle sprain.

• An ankle sprain is an injury to the ligaments, which connect bones to one another.
• In most cases, the ankle is twisted inward, causing small tears in the ligaments. The tearing leads to swelling and bruising, making it difficult to bear weight on the joint.

In addition to ankle sprains, ankle pain can be caused by:

• Damage or swelling of tendons (which join muscles to bone) or cartilage (which cushions joints)
• Infection in the ankle joint
• Osteoarthritis , gout ,rheumatoid arthritis , Reiter syndrome , and other types of arthritis

Problems in areas near the ankle that can cause you to feel pain in the ankle include:

• Blockage of blood vessels in the leg
• Heel pain or injuries
• Nerve injuries (such as tarsal tunnel syndrome or sciatica )

Home Care

To treat an ankle sprain:

• Rest your ankle for several days. Try NOT to put much weight on your ankle.
• Put on an ACE bandage. You also can buy a brace that supports your ankle.
• Use crutches or a cane to help take the weight off a sore or unsteady ankle.
• Keep your foot raised above the level of your heart. When you are sitting or sleeping, place two pillows under your ankle.
• Ice the area right away. Apply ice for 10-15 minutes every hour for the first day. Then, apply ice every 3-4 hours for 2 more days.
• Try acetaminophen or ibuprofen for pain and swelling.

As the swelling and pain improve, you will need to keep extra stress off your ankle for up to 10 days for a milder sprain and 2 to 5 weeks for a more severe sprain.

The injury may take a few weeks to many months to fully heal. Once the pain and swelling are mostly gone, the injured ankle will still be a little weaker and less stable than the uninjured ankle.

Call your health care provider if

Go to the hospital if:

• You have severe pain even when you are NOT bearing weight.
• You suspect a broken bone (the joint looks deformed and you cannot put any weight on the leg).
• You can hear a popping sound and have immediate trouble using the joint.

Call your doctor if:

• Swelling does not go down within 2 - 3 days
• You have symptoms of infection -- the area becomes red, more painful, or warm, or you have a fever over 100 °F
• The pain does not go away after several weeks
• Other joints are also involved
• You have a history of arthritis and are having new symptoms

What to expect at your health care provider's office

Your doctor will perform a physical examination, including a detailed examination of the ankles, and will ask questions such as:

• Does the pain shift from joint to joint?
• Is the pain the same in both ankles?
• Did the pain begin suddenly and severely?
• Did the pain begin slowly and mildly and then get worse?
• Did the pain get better by itself in less than 6 weeks?
• Does the ankle feel warm to the touch?
• Does the ankle hurt when you are not bearing weight on it?
• Do you have any abnormal sensation in your foot?

Diagnostic tests that may be performed include the following:

• Aspiration of synovial fluid (fluid from the joint space) and synovial fluid analysis
• X-ray of the ankle and possibly the foot

Nonsteroidal anti-inflammatory medications (NSAIDs), special foot gear, or braces may be prescribed. Surgery is sometimes needed.

Prevention

• Lose weight if you are overweight. Extra pounds put strain on your ankles.
• Warm up before exercising. Stretch the muscles and tendons that support the ankle.
• Avoid sports and activities for which you are not properly conditioned.
• Make sure that shoes fit you properly. Avoid high-heeled shoes.
• If you are prone to ankle pain or twisting your ankle during certain activities, use ankle support braces. These include air casts, ACE bandages, or lace-up ankle supports.
• Work on your balance and do agility exercises.
