Morton's Neuroma is a common foot problem associated with pain, swelling and/or an inflammation of a nerve, usually at the ball-of-the-foot between the 3rd and 4th toes. Symptoms of this condition include sharp pain, burning, and even a lack of feeling in the affected area. Morton's Neuroma may also cause numbness, tingling, or cramping in the forefoot.
What causes painful Achilles tendon?
Various factors have been implicated in the precipitation of Morton's neuroma. Morton's neuroma is known to develop as a result of chronic nerve stress and irritation, particularly with excessive toe dorsiflexion. Poorly fitting and constricting shoes (ie, small toe box) or shoes with heel lifts often contribute to Morton's neuroma. Women who wear high-heeled shoes for a number of years or men who are required to wear constrictive shoe gear are at risk. A biomechanical theory of causation involves the mechanics of the foot and ankle. For instance, individuals with tight gastrocnemius-soleus muscles or who excessively pronate the foot may compensate by dorsiflexion of the metatarsals subsequently irritating of the interdigital nerve. Certain activities carry increased risk of excessive toe dorsiflexion, such as prolonged walking, running, squatting, and demi-pointe position in ballet.
Typically, there's no outward sign of this condition, such as a lump. Instead, you may experience the following symptoms. A feeling as if you're standing on a pebble in your shoe. A burning pain in the ball of your foot that may radiate into your toes. Tingling or numbness in your toes. It's best not to ignore any foot pain that lasts longer than a few days. See your doctor if you experience a burning pain in the ball of your foot that's not improving, despite changing your footwear and modifying activities that may cause stress to your foot.
A doctor can usually identify Morton's neuroma during a physical exam. He or she will squeeze or press on the bottom of your foot or squeeze your toes together to see if it hurts. Your doctor may also order an X-ray of your foot to make sure nothing else is causing the pain.
Non Surgical Treatment
You may need a metatarsal pad if wider shoes do not help relieve your Morton?s neuroma symptoms. A metatarsal pad will help spread your metatarsal bones and reduce pressure on your affected nerve as it travels under the ball of your foot. The placement of your metatarsal pad is important, and it is best placed by a foot care professional who has experience in the anatomy of the forefoot and Morton?s neuroma treatment.
If these non-surgical measures do not work, surgery is sometimes needed. Surgery normally involves a small incision (cut) being made on either the top, or the sole, of the foot between the affected toes. Usually, the surgeon will then either create more space around the affected nerve (known as nerve decompression) or will cut out (resect) the affected nerve. If the nerve is resected, there will be some permanent numbness of the skin between the affected toes. This does not usually cause any problems. You will usually have to wear a special shoe for a short time after surgery until the wound has healed and normal footwear can be used again. Surgery is usually successful. However, as with any surgical operation, there is a risk of complications. For example, after this operation a small number of people can develop a wound infection. Another complication may be long-term thickening of the skin (callus formation) on the sole of the foot (known as plantar keratosis). This may require treatment by a specialist in care of the feet (chiropody).
How can Morton?s neuroma be prevented? Do not wear tight shoes or high-heeled shoes for prolonged periods. Do wear shoes with a wide toe box so that your toes are not squeezed or cramped. Do wear athletic footwear with enough padding to cushion the balls of the feet when exercising or participating in sports.
