There are quite a few reports on internet that Taurine is helping many people with migraines. I had occipital neuralgia and it greatly calmed down the pain. I took 2000 mg twice a day untill it was gradually minimized. I think mine starts with very subtle anxiety that eventually translates to pain in back of neck and head. It hurts when I put my head on pillow.
I speculate that if you have osteoarthritis which is caused by systemic infection, that will also contribute. You can take minocycline for osteoarthritis.
I realize the neuralgia makes your life very miserable so I hope this added information will help solve the puzzle.
