Commonly associated with Metatarsalgia, Morton’s neuroma is an entrapment of the inter-digital nerve lying between the 1st and 2nd, 2nd and 3rd or 3rd and 4th metatarsal bones.
Morton’s neuroma may cause symptoms similar to Metatarsalgia, but may also cause numbness, tingling, and discoloration of the 2nd to 4th (lesser) toes.
Tight-fitting shoes tend to aggravate this condition because they squeeze the metatarsals together, pinching the nerve.
X-rays of your affected foot will not show a neuroma, as neuromas are made up of soft tissue. X-rays may be helpful, however, in helping rule in osteoarthritis or a stress fracture as the cause of your symptoms. Ultrasound and MRI are sometimes used to help diagnose neuromas.
