hello, I have been having dull headaches for about 3 weeks, suddenly last week i went on lunch at work and say down when all of a sudden I was so sleepy I could barely stay awake, i went home and slept for 5 hours, it didnt help and then got a full nights sleep and was still so tired my eyes didnt want to stay open. finally that afternoon it subsided but the headaches continued daily, now joined with occasional nausea, diarrhea, bloody nose and lightheadedness. I dont have insurance and cant afford to go in.
