My husband has had a headache for almost three days. It came on Wednesday evening, and by bedtime it was migraine strength. He moaned and tossed all night long. Thursday he had a headache all day, but was able to function enough to work. He took an excedrin migraine and it helped enough he could sleep for a few hours, then was up feeling weird and dizzy . Today he stayed home sick, because he was concerned about getting to work safely and can t do much without feeling dizzy. I m getting worried! He s 32, average height and weight, healthy, habit free. At times he has problems with low blood pressure when he stands up. He felt he had a bit of a cold last weekend, but no cough, congestion or other symptoms. What can possibly be going on??
