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.
The source of this pain is an enlargment of the sheath of an intermetatarsal nerve in the foot. This usually occurs in the third intermetatarsal space, the space between the third and fourth toes and metatarsals. It occurs here, at the site third intermetatarsal nerve, since this intermetatarsal nerve is the thickest being comprised of the joining of two different nerves. It also may occur in the other intermetatarsal areas, with the second interspace being the next most common location.
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.
Based on the physical examination, your doctor usually can diagnose a Morton's neuroma without additional testing. A foot X-ray may be ordered to make sure that there isn't a stress fracture, but it will not show the actual neuroma. If the diagnosis is in doubt, your doctor may request magnetic resonance imaging (MRI) of the foot.
Non Surgical Treatment
Treatment for Morton's neuroma may depend on several factors, including the severity of symptoms and how long they have been present. The earlier on the condition is diagnosed, the less likely surgery is required. Doctors will usually recommend self-help measures first. These may include resting the foot, massaging the foot and affected toes. Using an ice pack on the affected area (skin should not be directly exposed to ice, the ice should be in a container or wrapped in something) Changing footwear, wearing wide-toed shoes, or flat (non high-heeled) shoes. Trying arch supports (orthotic devices). A type of padding that supports the arch of the foot, removing pressure from the nerve. The doctor may recommend a custom-made, individually designed shoe-insert, molded to fit the contours of the patient's foot. There are several OTC (over the counter, non-prescription) metatarsal pads or bars available which can be placed over the neuroma. Taking over-the-counter, non-prescription painkilling medications. Modifying activities, avoiding activities which put repetitive pressure on the neuroma until the condition improves. Bodyweight management,if the patient is obese the doctor may advise him/her to lose weight. A significant number of obese patients with foot problems, such as flat feet, who successfully lose weight experience considerable improvement of symptoms.
Surgical treatment has provided relief in some cases while poor results and surgical complications have resulted in other cases. It is believed that ligament weakness, as opposed to the pinching of nerves in the foot, may be to blame for recurrent pain in these situations. For reasons which are not fully understood, the incidence of Morton?s Neuroma is 8 to 10 times greater in women than in men.
