My Mom had them continually going through menopause (but no hot flashes) - she was in constant pain until put on something which is no longer on the market! I have only had a few I would consider genuine migraines that take over your existence - one at 16y & 30,000 ft where co-pilot asked my mom if they needed to get me an ambulance. I guess altitude makes them worse. My poor DD had many before being diagnosed with behcets which comes with headaches worse than migraines.... hard to believe - but so the neuro says! She has been on topamax which keeps them at bay. She went from 4-6 intractable headaches weekly to one every few months. Many woman find that works for them while their hormones are adjusting. May be worth checking into with your doc or consult with a neuro if you have them often... not fun!! Mom had to keep everything dark and quiet!
Take care! no worries at this end
