Anyone who has been diagnosed with HC if you can stomach indomethacin you'll feel better than you have before.
Anyone who can't stomach indo, nerve block injections help for a few day. There's a treatment called gamma core that Stimulates the Vagus nerve that might work for you. I currently use a TENs machine for my neck and forehead, this helps a little while its on but pain quickly returns once off. (Don't let my experience stop you from trying)
