Quick answer: A stellate ganglion block (SGB) is a minimally invasive injection of local anesthetic around a cluster of sympathetic nerves in the neck. By calming an overactive fight-or-flight response, it can relieve certain chronic pain conditions such as CRPS and neuropathic pain, and it is also used to help with anxiety and PTSD symptoms.
How it works
Under ultrasound or fluoroscopic guidance, anesthetic is placed around the stellate ganglion in the lower neck, temporarily interrupting overactive sympathetic nerve signals and letting the nervous system reset. Relief can begin within minutes and last from weeks to months.
What it treats
- Chronic neuropathic pain, including complex regional pain syndrome (CRPS)
- Post-surgical and facial pain, such as trigeminal neuralgia
- Migraines and vascular headaches
- Circulatory conditions like Raynaud’s, plus emerging use for anxiety and PTSD symptoms
What to expect
SGB is an outpatient procedure that usually takes 15 to 30 minutes, followed by brief monitoring. Temporary effects on the treated side can include mild hoarseness, a droopy eyelid, or a warm sensation in the arm or face, and most patients resume normal activity within 24 hours.
Frequently asked questions
What conditions does an SGB treat?
CRPS and other neuropathic pain, certain headaches and facial pain, and circulatory issues; it is also used for anxiety and PTSD symptoms.
How long does SGB relief last?
From weeks to months, depending on the person and condition, and it can be repeated.
Is a stellate ganglion block safe?
It is generally safe when performed by an experienced specialist, and side effects are usually temporary.
If nerve-related pain hasn’t responded to other treatments, an SGB may help calm the pain signals. Schedule a consultation with Midwest Pain Clinics: call (402) 391-7246 or book online here.
