Ankle sprain is the stretching or tearing of the ligaments which connect the shinbones to the ankle and heel bones. They provide stability to the ankle joint. An ankle sprain is a common injury that occurs when you land on your foot awkwardly or when walking on an uneven surface. It occurs most frequently when you participate in sports or when you jump or run on an irregular surface. Ankle sprains can cause pain, swelling, tenderness, bruising, stiffness, and inability to walk or bear weight on the ankle.
The diagnosis of an ankle sprain is usually made by evaluating the history of the injury and physical examination of the ankle. X-ray of your ankle may be needed to confirm if a fracture is present. MRI might also be required.
