Morton's neuroma is the common name given to the nerve irritation that is found in the ball of the foot that may or may not be accompanied by an inter-metatarsal bursae (a bursa-neuromal complex). It is often associated with inflammation or degeneration and often occurs with constant pressure or irritation of the nerve from the surrounding bony structures or local bursas (fluid filled sacs). Morton's Neuroma can cause symptoms such as a sharp pain, burning even a lack of feeling in the ball of the foot and associated toes.
Unfortunately, the cause of Morton?s Neuroma remains unknown to researchers. It is likely that a variety of factors may play a role in the development of this condition, including the presence of chronic pain conditions like fibromyalgia. Factors that may contribute to the development of Morton?s Neuroma include Wearing improperly fitting shoes can cause pressure on your foot, leading to swelling around the toe nerves. High heels are of particular concern as they cause a large amount of weight to be shifted to the ball of the foot. Repetitive activities like jogging, walking, and aerobics can also place a lot of pressure on the feet. This could lead to Morton?s Neuroma. Having a previous foot or muscle injury may cause you to hold your foot in a poor position when walking, contributing to nerve inflammation. Some people are just born with poorly shaped feet. People with extremely low arches or "flat feet" may suffer from Morton?s Neuroma more than others.
Symptoms associated with a neuroma include a dull burning sensation radiating towards the toes, a cramping feeling, or even a stinging, tingling sensation that can be described as being similar to an electric shock. It is often worse when wearing shoes with most people finding the pain disappears when removing their shoes.
You should visit a doctor or podiatrist (foot doctor) if you have pain or tingling that does not stop. Your health care provider will examine your feet and will apply pressure on the spaces between the bones of the toes to determine the location of the foot pain. The doctor may order X-rays to rule out other conditions associated with foot pain, such as a stress fracture or arthritis. X-rays alone will not show whether or not a neuroma is present, so an ultrasound scan or magnetic resonance imaging (MRI) test may be done to confirm the diagnosis. A diagnostic procedure called an electromyography is sometimes used to rule out nerve conditions that may cause symptoms like those of associated with Morton?s neuroma.
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.
Recently, an increasing number of procedures are being performed at specialist centers under radiological or ultrasound guidance. Recent studies have shown excellent results for the treatment of Morton's neuroma with ultrasound guided steroid injections, ultrasound guided sclerosing alcohol injections, ultrasound guided radiofrequency ablation and ultrasound guided cryo-ablation.
