Tbh bads Im afraid I have no effing clue and neither does anyone else I dont think.
I self diagnosed taking 75mg aspirin and vit b supplement every morning about 3 months ago. It may have made the migraines a bit less severe, but no less frequent tbh. I also get them around period and also ovulation. though today's is chocolate related I suspect
Oh and if you find yourself a bit, ahem, squitty, around your period and/or migraines, try the aspirin and vit b. It has helped me on that front definitely.
Last time I went to the migraine clinic at the local hosp they said I could ask my gp about trying Candesartan as a preventative (a type of beta blocker). As it's one of the few preventatives Ive not tried, Im going to give that a go. Tbh Im utterly sick of having my life dominated and ruined by the fucking things. I feel like and am about as active as an old woman most of the time.
