Stellate ganglion block overview
Targeting nerve pain in the upper body
A stellate ganglion block involves injecting local anaesthetic into the sympathetic nerves on one side of the neck, adjacent to the larynx or ‘voice box’. The stellate ganglion is a star-shaped group of nerves and nerve tissue next to the C7 vertebra and is sometimes called the cervicothoracic ganglion.
Sympathetic nerves control autonomous functions of the body, meaning functions that are not consciously controlled, such as heart rate, sweating and blood flow. The sympathetic nerves in this area can also transmit pain signals from the neck and head and control functions such as swelling and sweating. They may therefore be involved in neuropathic pain syndromes.
A stellate ganglion block temporarily interrupts pain signals from this region of the body. The block can be therapeutic and used directly to treat pain. When used for pain management, a number of treatments may be required over several weeks. A stellate ganglion block may also be used to treat circulatory problems affecting the upper limb.
Stellate ganglion block indications and preparation
Preparing for your stellate ganglion block
A stellate ganglion block may be recommended for:
- Pain in the head, face, neck, chest or arm.
- Neuropathic pain syndromes.
You should avoid undergoing any other medical procedures, such as dental treatment or a colonoscopy, within 48 hours before or after a stellate ganglion block. You should also not have anything to eat or drink prior to the procedure. Please let us know ahead of the procedure if:
- You are taking any antibiotics.
- You have a pacemaker or defibrillator.
- You have any allergies.
- You are diabetic.
- You are ill, in which case we may need to postpone the procedure.
You should not drive yourself to or from the appointment, or drive during the 24-hour period immediately after the procedure.
After your stellate ganglion block
Recovery and follow-up after the procedure
After the procedure it is normal to experience some drooping of the eyelid on the same side of your face as the injection. This may be accompanied by a hoarse voice or a blocked nose. All of these symptoms clear up within a few hours. You will generally be able to return to normal activities the day after the procedure. You will be asked to complete a 24-hour pain diary.
Someone from the clinic will call you within 1-2 days of the procedure to organise a follow up appointment.
