My waife was in a car accident 9 months ago and has had contstant headache pain. In January, she was diagnosed with Occipital Neuralgia and was given a cortisone injection, - the pain got 10X worse. In February, she was diagnosed by another Doctor (Neorosurgeon), with the same condition and had a neve block performed, the pain increased by another 10X. She is now oin the hospital, the Neurodurgeon syas he can't perform surgery, pain management says they have nothing to offer. What are the alternatives? I have read abour Occipital Nerve sectioniong. Is that an option? If so, what is the efficacy? and possible side effects?
