Stellate Ganglion Block
The stellate ganglion nerves travel along both sides of your spine. They are associated with a wide range of bodily functions that you don’t consciously control. These include blushing, heart rate, sweating and the dilation of your pupils.
A stellate ganglion nerve block is an injection that numbs branches of nerves in your neck. This helps doctors find and treat a number of problems linked to the nerves. Treatment may require a series of injections.
