http://orthopedics.about.com/cs/sprainsstrains/a/anklesprain.htm What happens inside the ankle when it is sprained? An ankle sprain is an injury to the ligament in the ankle. The ligaments are structures that control excessive movement of the joint. When an ankle sprain happens, the ligament is stretched too far, and is either partially or completely torn. There are two broad categories of ankle sprain: h Inversion Ankle Sprains The most common type of ankle sprain occurs when the foot is inverted, falling inward. When this type of ankle sprain happens, the outer, or lateral, ligaments are stretched too far. There are three ligaments that attach to the outer side of the ankle. About 90% of ankle sprains are inversion injuries. Pain is always on the outside of the ankle, and there is usually no pain on the inside of the ankle joint. http://familydoctor.org/online/famdocen/home/healthy/physical/injuries/010.html How can ankle sprains be treated? Many doctors suggest using the RICE approach-- R est, I ce, C ompression, E levation--for treating ankle sprains (see the box below). RICE approach Rest --You may need to rest your ankle, either completely or partly, depending on how serious your sprain is. Use crutches for as long as it hurts you to stand on your foot. Ice --Using ice packs, ice slush baths or ice massages can decrease the swelling, pain, bruising and muscle spasms. Keep using ice for up to 3 days after the injury. Compression --Wrapping your ankle may be the best way to avoid swelling and bruising. You'll probably need to keep your ankle wrapped for 1 or 2 days after the injury and perhaps for up to a week or more. Elevation --Raising your ankle to or above the level of your heart will help prevent the swelling from getting worse and will help reduce bruising. Try to keep your ankle elevated for about 2 to 3 hours a day if possible. http://www.footphysicians.com/footankleinfo/ankle-sprain.htm

What Causes a Sprained Ankle? http://www.aafp.org/afp/20010101/93.html Classification of Ankle Sprains Grade Signs and symptoms I: partial tear of a ligament Mild tenderness and swelling Slight or no functional loss (i.e., patient is able to bear weight and ambulate with minimal pain) No mechanical instability (negative clinical stress examination) II: incomplete tear of a ligament, with moderate functional impairment Moderate pain and swelling Mild to moderate ecchymosis Tenderness over involved structures Some loss of motion and function (i.e., patient has pain with weight-bearing and ambulation) Mild to moderate instability (mild unilateral positivity of clinical stress examination) III: complete tear and loss of integrity of a ligament Severe swelling (more than 4 cm about the fibula) Severe ecchymosis Loss of function and motion (i.e., patient is unable to bear weight or ambulate) Mechanical instability (moderate to severe positivity of clinical stress examination) Adapted with permission from Lateral ankle pain.
