Trigeminal Nerve Block

What is it?

A trigeminal nerve block is an injection of medication that helps relieve facial pain. It’s used to treat:

  • Trigeminal neuralgia
  • Herpes zoster infection (or “shingles”) affecting the face
  • Other atypical facial pain syndromes

Trigeminal nerves are responsible for sensations in your face and for helping you bite, chew and swallow. Blocking these nerves can help you stop feeling facial pain.

What are the benefits?

Some patients report pain relief immediately after the injection, but the pain may return a few hours later as the anesthetic wears off. Longer-term relief usually begins in two to three days, once the steroid begins to work.
How long the pain relief lasts is different for each patient. Some may be pain-free for days or weeks. Usually people need a series of injections to continue the pain relief. Sometimes it takes only two injections; sometimes it takes more than 10. The relief tends to last longer with each treatment.
