I have had migraines so bad that last year my parents had to rush me to the ER, I tried to take a hot shower and threw up allover, I ended up throwing up so much i became dehyrated and had to stay in the hospital overnight, I think it was caused by stress, i tried everything i could think of, cold wet rags, hot shower, medicine, nothing worked but they put this other medicine in my IV and that actually was the only thing that would help me.
