Your ankle joint is an intricate network of bones, ligaments, tendons and muscles. Strong enough to bear your body weight, your ankle can be prone to injury and pain. You may feel ankle pain on the inside or outside of your ankle or along the Achilles tendon, which connects the muscles in your lower leg to your heel bone. Because ankle pain can sometimes indicate a serious problem, severe ankle pain should be evaluated by your doctor, especially if it follows an injury. Most ankle pain, is the result of a sprain, which occurs when your ankle rolls your foot, causing an ankle ligament to stretch or even tear. Though sprains are often sports related, they can occur when you walk on an uneven surface.
