There are two kinds of nerve blocks:
1. Central (transforaminal) epidural nerve root blocks, which target the level of the spine pain generator (the disc).
2. Peripheral nerve blocks which target the many sources of peripheral pain such as lateral hip, shoulder, and knee just to name a few.
Nerve blocks are frequently used by pain management specialists to diagnose the exact level from which the pain originates. They can also decrease inflammation around the nerve which will then remove the radicular or sciatic pain patients’ experience.
