Also known as "dropped metatarsal heads," metatarsalgia can cause abnormal weight distribution due to over pronation. Metatarsalgia causes one of metatarsal joints to become painful or inflamed. People often develop a callus under the affected joint.

Metatarsalgia can also be caused by arthritis, foot injury (sports, car accidents, repeated stress), hard surfaces (cement or tile floors) and specific footwear (rigid soled work boots). Inappropriate shoes will only aggravate the condition.

A simple change of shoes may solve the problem. In more severe cases, full-length custom-molded foot orthoses may need to be prescribed.
