A sprained ankle is a common medical condition where one or more of the ligaments of the ankle is torn. Ankle sprains occur usually through excessive stress on the ligaments of the ankle. This can be caused by excessive external rotation, inversion, or eversion of the foot caused by an external force.
Symptoms of a sprained ankle can include pain, swelling, and bruising around the ankle, as well as difficulty walking or putting weight on the affected foot. The severity of the sprain can range from mild to severe, depending on the extent of ligament damage. Treatment for a sprained ankle typically involves rest, pain medications, braces, or surgery for severely torn ligaments.
