Morton's neuroma is a swollen, inflamed nerve in the foot.Morton's neuroma causes a "burning" sharp pain on the bottom of the foot. Treatments for Morton's neuroma include resting the foot, better-fitting shoes, anti-inflammation medications, ice packs, and operation. A neuroma is growth (benign tumor) that arises in nerve cells. A Morton's neuroma is a swollen, inflamed nerve located between the bones at the ball of the foot. The most common location of a Morton's neuroma is in either the second or the third spacing from the base of the big toe.
Morton's Neuroma is a foot condition caused from an abnormal function of the foot that leads to bones squeezing a nerve usually between the 3rd and 4th metatarsal heads. Symptoms of Morton's Neuroma often occur during or after you have been placing significant pressure on the forefoot area, while walking, standing, jumping, or sprinting. This condition can also be caused by footwear selection. Footwear with pointed toes and/or high heels can often lead to a neuroma. Constricting shoes can pinch the nerve between the toes, causing discomfort and extreme pain.
Patients will feel pain that worsens with walking, particularly when walking in shoes with thin soles or high heels. Also, anything that squeezes the metatarsal heads together may aggravate symptoms, such as narrow shoes. A patient may feel the need to remove the shoe and rub the foot to soothe the pain.
Metatarsal bones will be examined clinically, and often an x-ray will be taken to assess the particular case and ensure against other conditions, including fracture. When the foot is examined by a doctor, he may feel a characteristic ?click,? referred to as Mulder?s sign, and the interspaces between toe bones will often be tender. The doctor may put pressure on these areas to localize the site of pain and test for other conditions, including calluses or stress fractures. Range of motion tests will also be applied to rule out arthritis or joint inflammations. X-rays may be required to ensure there are no stress fractures or arthritis within the joints that join the toes to the foot. Tenderness in one or more metatarsal bones may imply a pre-stress fracture or stress-fracture. An ultrasound scan may be used to confirm diagnosis of Morton?s Neuroma, as x-ray will not detect the condition, (but can confirm that the bones are uninjured).
Non Surgical Treatment
Conservative treatment involves a reduction in the inflammation and removing the impingement factor. Reduction in inflammation is achieved via rest, elevation, ice, and massage with anti-inflammatory gels. Removing foot wear and and/r wearing broad type footwear would also help. Injection therapy is useful in reducing symptoms but not very successful in providing long term relief. The only time when it is most appropriate is when the cause of the space occupying object is not a neuroma but an inflamed bursa. Injection would help to relieve symptoms, and often cortisone is not even necessary.
If conservative treatment does not relieve your symptoms, your orthopaedic surgeon may discuss surgical treatment options with you. Surgery can resect a small portion of the nerve or release the tissue around the nerve, and generally involves a short recovery period.
The best way to prevent a neuroma is by avoiding the things that cause them. Review your risk factors. If relatives have had similar problems, or if you know that you pronate or have any problem with the mechanics of your foot, talk with a podiatric physician about the correct types of shoes and/or orthoses for you. If you are not sure whether you have such a problem, the podiatric professional can analyze your foot, your stride and the wear pattern of your shoes, and give you an honest evaluation. Remember, though, that sometimes neuromas, like other conditions, can develop for no discernible reason. With this in mind, be good to your feet, and be aware of any changes or problems. Don?t wait to report them.
