ICD 10 - M19.91
A neuroma is a thickening of the tissue that surrounds a nerve. A morton’s neuroma is a specific neuroma in the toes between the third and fourth toes. A neuroma can also occur in other parts under the ligaments of the metatarsals and of the foot. Morton’s neuroma is 8-10x more likely to occur in women than in men. High-heeled shoes and tapered toe boxes in the shoe are thought to be common causes for this pathology.
- Tingling, burning or numbness in the metatarsals radiating out toward the toes
- A sensation of a lump inside the forefoot
To confirm a diagnosis, a clinician will observe the patient’s past medical history, perform a physical examination and possibly order imaging studies to see the extent of the damage around the nerve.
For most mild cases of neuromas, treatment will be conservative and nonsurgical. A normal treatment plan can include padding under the arch of the foot, icing, wearing orthotics, modifying the type of shoes worn, NSAIDs and modifying daily physical activities. Surgery may be a possible treatment for patients that have seen no benefit from conservative care and have developed a late stage neuroma.
