Also referred to as Metatarsalgia, a stone bruise is a condition that affects the forefoot. This is the area between the toes and where the foot arcs. A stone bruise is characterized by pain and inflammation on the forefoot or the metatarsal, and more so between the phalanges. This condition occurs when two phalanges misalign and push against a nerve ending, therefore compressing it. It brings irritation to the surrounding nerves, causing them to be inflamed. A scar-tissue layer automatically forms around this area as the body seeks to protect these nerves.
