Interdigital Nerve Block

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.

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.

The pain will return later that day as the local anesthetic wears off. Longer-term relief is obtained with the corticosteroid.

How long the pain relief lasts varies person to person. For some, the relief lasts several days to months. If the treatment works for you, you can have periodic injections to stay pain-free.

The risk of a complication from an interdigital nerve block is very low. Rarely, complications include bleeding or infection at the injection site, which is unusual for this kind of injection. Most of the time, these effects resolve within a few hours.

It is okay to be active the day of the procedure. There are no specific restrictions for this particular procedure. Do not drive the day of the injection if you have had any form of anesthesia.

You can continue your regular diet and medications immediately.

Please record your percentage of pain relief for the first 4-6 hours after the injection. Your response after this initial injection will be a major deciding factor in determining whether a confirmation injection is to be performed.
