Boyfriend got a headache at work yesterday, had some nausea and vomiting with it, came home about 6:30 and went to bed. Slept until 9:30 this morning, I asked him how he was still had a headache, have him excedrin, he went back to sleep. Had him wake up about 3 this evening to eat a cheeseburger and took more excedrin. a few hours later he had diarrhea and still has the headache. Is this all just a migraine??
