I wish that I did know something that caused it Bosco! The only thing that might have helped is that I got pregnant. I miscarried at 2+ months and the hormone change could have affected my CH, but I was too upset to notice, you know? They were gone after that event.
Then that brings up 'Well, why did they return?' Also, don't know. Can't blame my move north, as I had been living here for 6-8 months when they showed up. But looking back, I can recall two short cycles before the move. I had gotten a concussion a short time before the first cycle.
My first 20 years, I was a low level chronic, undiagnosed. I was on Elavil and one other med whose name escapes me at the moment. Inderal I think. So, I had no idea that I had CH or that they came in two varieties.
That cycle was short, but hell none the less and the second one sent me diving into 'what is this????' Then I took the the printout of CH to my doctor. Carbemazepine was prescribed at that time. He had been on the Migraine bench till then. I had tried trex once and thrown it out due heartbeat issues bugging me.
Additionally both little cycles I had then were thought to be 'other' things and were treated with Pred of all things and that killed them. Funny how that worked out. As it was, they were both about 2 weeks duration.
Girl, you are making me think too darn hard for this early!!!
