Long COVID:
Long COVID refers to a range of persistent symptoms that some individuals experience after recovering from an acute COVID-19 infection. These symptoms can include fatigue, brain fog, shortness of breath, and various neurological and autonomic dysfunctions. While the underlying cause of long COVID are still not fully understood, research suggests that dysregulation of the autonomic nervous system (ANS) plays a role. The stellate ganglion is part of the ANS and by blocking the ganglion the procedure helps regulate the uncontrolled autonomic activity and alleviates the symptoms associated with long COVID.
Complex regional pain syndrome (CRPS):
Stellate ganglion blocks are used to treat individuals with CRPS, a chronic condition characterized by severe pain, swelling, and changes in skin color and temperature. This block interrupts the abnormal sympathetic nerve activity associated with CRPS and provides pain relief.
Sympathetically Maintained Pain:
Stellate ganglion blocks can be used to manage pain originating from sympathetic nerves, Examples include pain caused by nerve injuries, phantom limb pain, and postherpetic neuralgia (nerve pain after shingles).
Vascular conditions:
Stellate ganglion blocks can be utilized in the treatment of certain vascular conditions like vascular insufficiency, thoracic outlet syndrome, acute frostbite, etc. It can also be useful for the treatment of Raynaud’s disease, which causes narrowing of blood vessels in response to cold temperatures or stress. By blocking sympathetic nerve activity, blood flow to the affected area can be improved.
Excessive sweating (hyperhidrosis):
Stellate ganglion blocks have been used to treat excessive sweating in the upper extremities by inhibiting the sympathetic nerves responsible for regulating sweat production.
