Hi, have just come across this forum as I'm trying to work out what is happening with this new horror with my head. I had suffered from classic episodic migraine with aura since my teens, which was mainly manageable until about six years ago when I had a major flare up and several hospital trips and many tests. In the end the diagnosis was chronic migraine and the pain never actually went away until I was finally approved for Botox to treat it which has mainly kept it under control. Now about 2-3 weeks ago I have started with these new episodes which seem to fit the description of cluster headaches. They fit the description in that they are intensely, ridiculously painful, start behind my left eye and radiate down my face into my jaw and teeth and nothing is relieving them. They were at approximately the same time every evening though and now they seem to have progressed to random times throughout the day. Is this normal? Also is it normal to have pain in-between attacks, just to a lesser intensity? And I have a permanent metallic taste in my mouth and my tongue keeps tingling sporadically - is this a cluster headache symptom. Apologies for all the questions - just trying to find the likely diagnosis and any treatment that might help slightly before my life implodes again like it did last time!
