Common Nerve Conditions in the Foot

Nerves play a critical role in how we experience pain, balance, and movement. Nerves are two-way messaging electrical conduits that carry signals for motor function from the brain to the periphery, and sensory input, carrying information from the periphery to the brain. When there is a disturbance either mechanically or chemically in the signal pathway, symptoms can emerge.

Systemic conditions such as diabetes and autoimmune disorders can lead to nerve dysfunction, or peripheral neuropathy. Symptoms of neuropathy may include burning, stinging, compressive pressure, pins and needles, or even combinations of symptoms. Often the presentation will be insidious, developing slowly over time. However the symptoms can become profound and persistent, affecting quality of life. Treatment begins with identifying the underlying cause and if possible treating that condition, with nerve symptoms resolving when the underlying disorder is reversed. In some cases, such as with diabetic neuropathy, there is no reversal as the nerve damage becomes permanent.

Mechanical compression is another common cause of nerve pain in the foot. Morton's neuroma and tarsal tunnel syndrome are two examples of this. Electrical shock, tingling, and abnormal sensations hallmark these conditions. Generally, pressure relief has beneficial effects. Occasionally the pressure needs to be relieved with surgical means. This involves decompressive surgery.

In season 2, we will dive deeper into surgical management of nerve conditions and many others. This episode will touch on symptoms and workup.
