What's the cure for occipital neuritis?

Injection: Although the pain of greater occipital neuritis can respond to analgesic meds, I have found that localized nerve blocks, even local cortisol may reverse and stabilize indefinitely. A permanent solution may be associated with an alcohol injection, but this will leave some numbness over the ear.

I agree. But...: I inject 2% xylocaine (lidocaine) with Dexamethasone or Betamethasone suspension. I get very good results. I have never seen a person needing chemical or surgical nerve ablation!

Yes: Occipital neuralgia is a treatable disease. Injections (either nerve blocks or botox) are a good diagnostic tool and may relieve pain for days to weeks. If these work, surgical decompression of those involved nerves - the greater and lesser occipital - can significantly reduce or relieve pain in those patients.
