I in fact suffer from Hemiplegic migraines they are not nice to have nor would like to hear of anyone having them.
I could be sitting at home or out and about and BAM!! it hits me and i literally have to be driven home and put in a dark room by myself for a few hours until i calms enough the main thing that causes my migraines to hit is low blood sugar, lack of sleep, low protein.
I feel sorry for anyone who does get severe headaches or migraines because I do know what they are like.
