Metatarsalgia: describes a painful foot condition characterized by inflammation under the “lesser balls” of the foot near the toes. Besides pain on the balls of your foot, other symptoms may include numbness and tingling in the toes, sharp pain that is worse when you flex your foot, and a feeling that you have a bruise in your foot or are walking on a stone.
Metatarsalgia is commonly caused by improper function related to a loss of the arch height and a flat foot posture. When you lose the arch, too much weight is shifted to the 2nd, 3rd and 4th metatarsal heads which are not designed to take such repetitive loads. Since the primary cause of metatarsalgia is a loss of normal foot function, the best solution is to restore function with a custom orthotic that completely supports the restored arch of your foot.
