Morton's neuroma, also called Morton's metatarsalgia, Morton's disease, Morton's neuralgia, Morton metatarsalgia, Morton nerve entrapment, plantar neuroma, or intermetatarsal neuroma is a benign (non-cancerous) growth of nerve tissue (neuroma) that develops in the foot, usually between the third and fourth toes (an intermetatarsal plantar nerve, most commonly of the third and fourth intermetatarsal spaces). It is a common, painful condition.
It's not always clear what causes Morton's neuroma, but several things seem to aggravate it. These include other foot-related problems and wearing restrictive footwear. It's thought that Morton's neuroma may be caused by the toe bones (metatarsal bones) pressing against the nerve when the gap between the bones is narrow. This causes the nerve and surrounding tissue to thicken.
Morton's neuroma can cause a very painful burning or sharp pain in your foot that feels worse when you walk. It may feel like a small lump inside the ball of your foot. It is usually between the third and fourth toes, but it can also be between other toes.
If you suspect Morton?s Neuroma, it is essential that you confirm your suspicions by consulting with a podiatric physician. Don?t wait for the symptoms to go away for good (even if they tend to come and go). Also, remember that many conditions have similar symptoms, and only a professional can tell the difference.
Non Surgical Treatment
Rest. Continuing with normal training will increase pain and inflammation and prevent the injury from healing. Wear a metatarsal pad under the forefoot which will raise and spread the bones of the forefoot taking the pressure off the nerve. Wearing metatarsal pads in the shoes under the forefoot spreads the metatarsals creating more space for the nerve. See a sports injury professional who can advise on treatment and rehabilitation. Orthotic inserts may be required to correct any biomechanical dysfunction of the foot.
Surgery is occasionally required when the conservative treatment is not able to relieve your symptoms, particularly if you have had pain for more than 6 months. 80% of patients who require surgery report good results, with 71% of people becoming pain-free.
To help reduce your chance of developing Morton's neuroma avoid wearing tight and/or high-heeled shoes. Maintain or achieve ideal body weight. If you play sports, wear roomy, properly fitting athletic footwear.
