I have had multiple traumatic injuries to my head/neck from ages 12-22 and significant pain since age of 30 and am now 58.
I have C-2 pain distribution and C-2 nerve root block was positive for pain. A C-2 ganglionectomy is recommended. There is little (or current) information on this procedure. I would like to talk to someone who has this type of pain and see what their experiences with treatment/sugeries are.
There is a great article under website of Dr. Jho.com under "occipital neuralgia" (describes me to a T) where he does not believe in ganglionectomy procedure but instead a minimally invasive C-2 decompression.
I have consulted with Dr. Jho who would only do it on me after first doing a C5-6 anterior foraminotomy as I have C5-6 stenosis. I have various problems all up and down my spine and states he will start only with problems he can identify and see by MRI. Epidural injections all up the spine only provide minimal and short-term relief at the C1-2 level. Occipital injections provide no relief.
