Morton's neuroma is a condition that affects one of the nerves that run between the long bones (metatarsals) in the foot. The exact cause is not certain. Symptoms include pain, burning, numbness and tingling between two of the toes of the foot. About a quarter of people just need simple treatments including modification of their footwear. Sometimes surgery is needed for long-standing (chronic) symptoms.
A Morton's neuroma commonly occurs due to repetitive weight bearing activity (such as walking or running) particularly when combined with tight fitting shoes or excessive pronation of the feet (i.e. "flat-feet"). The condition is also more common in patients with an unstable forefoot allowing excessive movement between the metatarsal bones. A Morton's neuroma can also occur due to certain foot deformities, trauma to the foot, or the presence of a ganglion or inflamed bursa in the region which may place compressive forces on the nerve.
The primary symptoms include sharp, shooting pain, numbness or paresthesia in the forefoot and extending distally into the toes, typically in the region of the third and fourth toes. Symptoms are aggravated with narrow toe box shoes or those with high heels. There is usually a reduction of symptoms when walking barefoot or wearing shoes with an appropriately wide toe box. Symptoms are also aggravated with shoes that are tied too tight.
Diagnosis of Morton?s Neuroma typically involves a physical examination of the affected foot. Your health care provider will ask you about your symptoms and examine your feet and toes. He will manipulate your toes, pushing them from side to side and squeezing on the spaces in between. This physical exam will allow your health care provider to feel for any lumps that may be present under the soft tissue of your feet. Your health care provider may also listen for any clicking sounds that your bones may be making. Known as Muldor?s Sign, this clicking is common amongst sufferers of foot neuroma. Occasionally, an x-ray or MRI (magnetic resonance imaging) is performed to help rule out any breaks, sprains, or fractures in your foot.
Non Surgical Treatment
It can be helpful to perform deep stripping massage techniques along the length of the tibial nerve and the medial and lateral plantar nerves. After properly mobilizing these tissues, moving the foot and toes through a full range of motion to make sure the nerve can move freely will also be helpful. Foot pain like that occurring in Morton's neuroma, can become a debilitating and painful condition. And while massage can be helpful for this condition, it is also clear that improperly applied massage can aggravate it and make it worse. Consequently it is crucial that we use good clinical reasoning and appropriate evaluation methods to most effectively help these clients.
For those who are suffering severely with Morton?s Neuroma, surgery is a possibility. An orthopedic surgeon can remove the growth and repair your foot relatively easily. However, Morton?s Neuroma surgery is associated with a lengthy recovery time and there is a possibility that the neuroma may return.
