Depending on the location, corns are divided into categories of hard and soft. Hard corns are typically lesions that are located on the dorsum of toes having an underlying claw toe and hammertoe deformity. By definition , metatarsalgia is pain under the ball of the foot. Typically, the symptoms are localized in the metatarsal head area. The symptoms are caused by either increased pressure applied by deformities or by atrophy of the plantar fat pad.
