I have these HA spells that always involve my R-temple & eye area. These HA come on quickly with little warning. The pain is incredibly intense. Horrible! My R-eye turns red, waters, blurs, and vision is difficult as it wants to completely close! I can't take this! I even tried standing on my head, ice, and enough ASA til my ears start to ring! If I had hair, I'd be pulling it out! Thanks for any information you can give me! Sean -
