I have had shots in freeze nerves in my neck before determining if it would be useful to have them cauterized. It didn't help. I get extremely stiff neck along with frontal headaches and I notice are connected to physical and environmental stimulation. I get a mild attack after eating. No meds really help and lying down / sleeping is the best cure. They wanted to do surgery on my neck but given they were wrong with the first diagnosis treatment I am reluctant. I think it is neurological because when it's bad I also get strong light auras. I have a neurologist who referred me to a pain specialist who pursued the neck. Think I'd rather find a neurologist who will focus more on the brain / neurological system.
