Nerve blocks are injections of medication onto or near nerves, which block pain signals. Nerve blocks are used to relief pain from a variety of conditions, from a broad range of locations on the body. The medications that are injected include local anesthetics, steroids, and opioids.

TRIGEMINAL NERVE BLOCK
The trigeminal nerves supply the front half of the head, including the face, mouth and tongue. They allow us to bite, chew and swallow, and they also produce the sensations you feel in your face. When these nerves are compressed, deteriorate, or get damaged, they can cause pain. Blocking them can help relieve pain symptoms from conditions like trigeminal neuralgia, herpes zoster, and other atypical syndromes that cause facial pain.
