Yup. Same. Doctor's say there is no cause and no cure. It just is.
HOWEVER! My mom recently told me about a coworker of hers who has suffered from migraines EVERY SINGLE DAY since she was 13 years old. She considered suicide multiple times throughout her life, and one day someone suggested botox. Yes, botox. Injections to the forehead. Apparently, some of us tense up our foreheads while we sleep, causing the migraine that is present by the time we wake up. So botox to the forehead prevents that from happening. She has been completely migraine free every since she began weekly botox treatments.
I dunno, but it's something to consider.
