Metatarsalgia (Ball-of-foot pain)
Metatarsalgia is pain in the plantar forefoot metatarsal area.
This condition usually causes a burning sensation in the plantar forefoot region. Sometimes patients may describe the pain as a lump underneath the ball of the foot. Applying pressure to the plantar surface of the metatarsal heads may elicit pain.
A progressive weakening of the soft tissue structures occurs when a foot is pronated excessively for any length of time. As this occurs in the forefoot, the metatarsals plantar flex and rotate.
This results in shearing forces on these foot structures. After a period of time, the foot may experience nerve damage or callosities.
