Peripheral nerve blocks

Peripheral nerve blocks, like the shot of novocaine at the dentist's office, act on a nerve outside the central nervous system (the brain and the spinal cord). Either an individual nerve or a cluster of nerves (nerve plexus) is injected.

Common examples of peripheral nerve blocks used for people with cancer pain include:
intercostal (between the ribs) for pain on the wall of the chestbrachial plexus (a group of nerves near the armpit) for pain in one armtrigeminal (a nerve to the head and face) for specific types of facial pain.
