Pain Treatments

Interdigital Nerve Block

There is a nerve that travels along the inside and outside of each toe. This nerve is called the interdigital nerve. Sometimes this nerve can become inflamed as a result of pressure when the base of the toes rub against each other. This condition is also referred to as Morton’s neuroma. An interdigital nerve block is a procedure in which an anesthetic solution is injected into the base of the toe to provide immediate pain relief to the inflamed nerve.

How is an interdigital nerve block performed?

The doctor will numb the skin over inside and outside of the base of the affected toes with medication. Then, guided by palpation, he will:

  • Insert a thin needle to the space between the toes

  • Inject numbing medication (for short-term pain relief) and corticosteroid (for long-term pain relief)

Usually, the procedure takes less than 15 minutes and you can go home the same day.
