Suffered from them since I was 13, and SICK of them to be honest. I've been prescribed/recommended three different strong painkillers (not to take all at the same time, obvioiusly) and I've tried them all (lucky enough for me I have enough hemiplegic migraines to try them all out pretty quickly) and nothing seems to work. And worst of all I get NO warning, I just start getting blind spots in one eye, and end up going blind in one eye, then one side of my body goes numb and I can't talk, walk or do anything. My mouth just slacks and I can't even move my lips properly. Last time it lasted for about 10 hours and I've been having a lot of headaches and problems sleeping since. Does anyone suffer from these and have a way of preventing or stopping them? Alsooo, heard that if you get two within a 24 hour period or so you should call 999, can anyone tell me if this is true?
