Morton’s Neuroma is another type of peripheral nerve problem in the foot caused by repetitive compression of the common plantar digital nerve. This nerve lies between the heads of the metatarsal bones. The neuroma that develops is not a true neuroma but rather a chronic nerve compression. The nerve actually thickens and becomes bulbous. High heels and tight shoes can increase this type of pain. Patients usually complain of tingling or burning or numbness in the ball of the foot. The third and fourth toes are most often affected. A feeling of a ball or mass on the bottom of the forefoot is not uncommon. Multiple neuromas are possible in the same foot.
Diagnosis and Testing
Following a podiatric neurologic examination two options to clinically determine if a neuroma diagnosis is correct are available:
Ultrasound and PSSD testing
At North Jersey Podiatry we offer the latest in Ultrasound technology to view the soft tissue detail of your foot, similar to an MRI. Additionally the use of PSSD (pressure specified sensory device) to measure the function of your nerves is performed. This test is non-painful and non- invasive that quantifies the sensory loss of the nerve. This test will verify the patient doesn’t have problems with other nerves and the Morton’s Neuroma is an isolated problem. The PSSD can also help identify those individuals who have been misdiagnosed as having a Morton’s Neuroma and actually have a mild early Neuropathy.
