Metatarsalgia (Pain in the ball of the foot) is not an injury; it is a symptom or a group of symptoms. These may include pain in the ball of the foot, with or without bruising, and inflammation. Metatarsalgia can have a number of causes and, as a result, a number of treatments.
Some of the best treatments come from being proactive. A regular checkup with a podiatric physician who can assess other risk factors, such foot shape, also will allow you to take preventive measures. Treatment is generally conservative.
