yes, I have been thinking I have had the flu for 6 days now. First I had 2 days of throwing up and diarehea and in that time I gained 10 pounds of fluid. I have drank alot of water and pedialyite these last 6 days. Then on tuesday I was still feeling like the flu but now was getting a migraine. I have them as well as intracranial hypertension. I still have the migraine but now I am burping up a charcoal taste and feel like i need to poop and cant. I am cramping alot especially on the left side. Is this usual or do I need to go the hospital
