Detailed explanation-1: -The benefit of the stellate ganglion block varies from patient to patient, but it may last up to several weeks. Repeat injections are often considered if the initial block was considered helpful.
Detailed explanation-2: -The stellate ganglion is shaped like an oval but may also look like a star (“stellate” means “star”). The stellate ganglion provides most of the sympathetic nerve signals to your head, neck, arms and a portion of your upper chest. Your sympathetic nervous system is part of your autonomic nervous system.
Detailed explanation-3: -There are some expected changes that result from blocking the sympathetic nerves. These changes are temporary and may last about 4-6 hours. Such changes include the following symptoms on the same side as the injection: drooping of the eyelid, bloodshot eye, stuffy nose and a temperature increase in the arm.
