sympathetic blockade

Sympathetic blockade is a medical procedure used to interrupt nerve signals in the sympathetic nervous system, which controls functions like heart rate and blood vessel constriction. This is typically done through injections of anesthetic or medication near specific nerves. By blocking these signals, doctors can help alleviate pain, reduce sweating, or manage conditions like hyperhidrosis or complex regional pain syndrome. Essentially, it’s a way to temporarily "turn off" certain nerve pathways to improve a person's comfort and quality of life.
