my husband just got a severe headache followed by dizziness, clammy skin, and he eventually throws up and has to quickly have a bowel movement. This all occurs within an hour. He had this about 2 weeks ago. He slept for about 10 hours then was fine. He doesn t drink, smoke, etc. He s 35 and has never really had headaches either. This just seems very odd that it does this in the same order, etc. any ideas
