sympathetic nerve block

A sympathetic nerve block is a medical procedure that targets specific nerves part of the sympathetic nervous system, which controls involuntary functions like blood vessel constriction. By temporarily numbing these nerves with medication, doctors can reduce certain types of pain, improve blood flow, or treat conditions like excessive sweating or circulatory disorders. The procedure involves injecting local anesthetic near the nerve bundle under imaging guidance, providing pain relief or symptom control without affecting other body functions. It's a targeted way to manage symptoms that originate from overactivity of these nerves.
