re: Anyone here experience Cluster Headaches?

Had them for years when I was younger. Got them every year for the whole months of July and February. Exactly started and ended those months. Weird. The only way I can describe the pain was it felt like a severe muscle cramp on the inside of one side of your head that you couldn't massage out. Hell on earth. Prednisolone pack (decreasing dose for a week) saved me.
