When I was asleep last night I was nauseaous with abdominal pain. I got up and took pepto bismal. The pains was upper abdomin. I laid back down but felt like I would throw up. I threw up 5 min later. It was grey and no sign of the pepto I took. I thought I would feel better since I threw up but my stomach feels really bloated/full. I get pains when I even sip water. I havent been hungry at all which is very unusual for me. I know have pain between my shoulder blades. What could it be?
