Maybe you all can help me. My headaches have been increasing in frequency also. Thinking back, I remember keeping ibuprofen in my desk at work in my 20s and using it often, but those were simple headaches which may or may not have been related to my cycle. Later, when I had Mirena I developed terriflying ocular migraines without any significant pain. I could always tell one was coming on if other cars' headlights had a funny look to them. Upon removal of the Mirena, the headaches disappeared for several years. Then, when I was still cycling, I began to get these 3 day headaches which would have been mid to late cycle. At that point my cycle was short so while they definitely weren't the day or two before my period they must have been after ovulation. Now with no cycle, I'm getting migraines any time, sometimes with flicker lights or visual problem aura, always with a prodrome uneasy feeling, and often with a postdrome hungover feeling. The actual headache responds well to ibuprofen, but as Hurdity described, returns after the med wears off. I usually get by with only taking a small 200mg of ibuprofen at the beginning of the pain, then once or twice more over the course of the 3 days. I consider this very manageable, but the prodromal and postdromal stages and lately the auras really bother me. I've never discussed with my doctor since the ibuprofen covers the ache. Do you all know if there is anything to be done for the pro- and postdrome and auras? The only thing HRT seemed to do for it was possibly made it more cyclical but more intense.
