It felt like there was a pit in my stomach at first from being hungry, so I ate some soup, but that just made the pain worse, like a sharp shooting feeling in the middle of my belly, around the bellybutton area. I took 800mg of Ibuprofen but ended up throwing that and everything else that was in my stomach back up. Pain got increasingly worse over an hour's time, then started sweating profusely despite feeling cold. Any suggestions?
