This condition is a lasting pain on the outer side of the ankle that often develops after an injury such as a sprain or fracture of the ankle.
The most common cause for chronic ankle pain is a failure of the ankle to heal properly after an injury. If the pain develops after a sprain, the affected ligament may remain weak after healing, causing instability and the chance for further injury.
Nerves and tendons may also be injured in the sprain, and scar tissue may develop, placing pressure on structures in the ankle.
The most common symptom is lasting pain on the outer side of the ankle, particularly when walking or when participating in sports or strenuous exercise. Other symptoms include difficulty walking, instability, swelling, stiffness and tenderness.
Treatment options include anti-inflammatory medication, physical therapy, use of a cast, splint or brace, and rest. If the pain continues for a considerable time after treatment, surgery may be required.
