Morton’s neuroma is a painful condition that affects the ball of your foot, most commonly the area between your third and fourth toes. Morton’s neuroma may feel as if you are standing on a pebble in your shoe or on a fold in your sock. Morton’s neuroma involves a thickening of the tissue around one of the nerves leading to your toes. This can cause a sharp, burning pain in the ball of your foot. Your toes also may sting, burn or feel numb. High-heeled shoes have been linked to the development of Morton’s neuroma. Many people experience relief by switching to lower heeled shoes with wider toe boxes. Sometimes corticosteroid injections or surgery may be necessary.
Although in many areas of medicine, it?s easy to pinpoint the exact source of a problem (the way a specific germ causes a certain illness with recognizable symptoms), neuromas are harder to categorize. While there isn?t really one exact cause, podiatric physicians tend to agree that a neuroma can occur in response to the irritation of a nerve by one or more factors. Abnormality in foot function or foot mechanics: In other words, a foot that doesn?t move the way science thinks it should. In general, this means a pronated foot (one with an excessive rolling motion when the patient is walking, running or doing any kind of activity), because it causes excessive strain on the nerve. If you are not certain whether or not this is a problem for you, ask your podiatric physician, who will be able to examine your feet, as well as the wear pattern on your shoe, and give you an answer. Foot mechanics, and problems with them, tend to run in families, so if you know that a relative has had foot pain similar to yours, be sure to mention it.
A Morton’s neuroma causes a “burning” sharp pain and numbness on the bottom of the foot in the involved area, and this pain and numbness can radiate to the nearby toes. The pain is usually increased by walking or when the ball of the foot is squeezed together and decreased with massaging. It may force a person to stop walking or to limp from the pain.
Podiatrists conduct a physical examination and may order imaging tests, such as x-ray or MRI scan to diagnose Morton’s neuroma. Conservative treatment options include custom-fitted orthotics, medication, and/or alcohol injections designed to harden the nerve. However, most patients with Morton’s neuroma need minor surgery.
Non Surgical Treatment
Nonsurgical treatment is tried first. Your doctor may recommend any of the following. Padding and taping the toe area, shoe inserts, changes to footwear, for example wearing shoes with wider toe boxes or flat heels, Anti-inflammatory medicines taken by mouth or injected into the toe area, nerve blocking medicines injected into the toe area, other painkillers, physical therapy. Anti-inflammatories and painkillers are not recommended for long-term treatment. In some cases, surgery is needed to remove the thickened tissue and inflammed nerve. This helps relieve pain and improve foot function. Numbness after surgery is permanent.
When early treatments fail and the neuroma progresses past the threshold for such options, podiatric surgery may become necessary. The procedure, which removes the inflamed and enlarged nerve, can usually be conducted on an outpatient basis, with a recovery time that is often just a few weeks. Your podiatric physician will thoroughly describe the surgical procedures to be used and the results you can expect. Any pain following surgery is easily managed with medications prescribed by your podiatrist.
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.
