Your ankle bone and the ends of your two lower leg bones make up the ankle joint. Your ligaments, which connect bones to one another, stabilize and support it. Your muscles and tendons move it.
Ankle pain can result from a large number of ankle and foot injuries, the most common ankle injuries are sprains (low and high ankle), which involve ligaments and bones in the ankle. But you can also fracture a bone, tear muscles or over-stress a tendon when you sprain your ankle.
