Sympathetic Nerve Blocks
Injections targeting the sympathetic nerve chain to interrupt abnormal pain signaling — most often used for Complex Regional Pain Syndrome (CRPS) and other sympathetically-mediated pain.
What unifies this category
The sympathetic nervous system regulates blood vessel tone, temperature, and sweating in the limbs — and in conditions like CRPS, it can become part of the problem, contributing to the abnormal vasomotor changes, swelling, and pain amplification that define the condition. A sympathetic nerve block interrupts that signaling with local anesthetic delivered at the relevant relay point in the sympathetic chain.
Which relay point depends entirely on which part of the body is affected. These are two distinct procedures at two different anatomical levels — a stellate ganglion block for the upper extremity, head, or neck, and a lumbar sympathetic block for the lower extremity — not interchangeable versions of the same injection.
