Metatarsalgia is a general name given to pain in the front part of the foot under the heads of the metatarsal bones. This is the area on the sole of the foot sometimes called the ball of the foot. Metatarsalgia can be caused by a number of different conditions affecting the foot. It is really a symptom of other problems rather than a specific disease itself.
