Doctors may order tests to evaluate how the muscles and nerves are functioning in order to locate and determine the extent of the nerve injury. These tests may include:

Electromyography measures muscle activity and response to nerve stimulation.

A nerve conduction study measures the speed and amount of electrical impulses that travel through a nerve.

Any of the following imaging techniques may also be ordered by the doctor:

CT scan




Depending on the location and degree of nerve damage, the doctor may prescribe different therapies. An underlying illness may cause the problem, so it is critical to address it.

Nonsurgical treatments, such as orthotics, braces, or foot splints that fit inside a person's shoe, can offer relief. Mobility can be improved through physical therapy and gait retraining.

Surgery on peripheral nerves may be required in some cases
