Synopsis

Neuropathic pain in the region of the metatarsus, most commonly between the third and fourth metatarsals, caused by interdigital nerve compression. It is not a true neuroma. Common signs and symptoms include numbness, hyperesthesia or paresthesia in the distal metatarsals, sensation of a pebble in the shoe, and aching or burning foot pain radiating from the metatarsal heads to the third and fourth toes, which may be associated with high heels, tight shoes, and overpronation.

Conservative management includes modifying activities involving the feet, choosing wider shoes, adding metatarsal pads, and custom orthotics for pain relief and to allow for healing. Other pain treatments are glucocorticoid and local anesthetic injection, alone or in combination, which may be more accurately guided by ultrasound.
