What Causes Pain Under The Rib Cage?

24 hours ago O started feeling pain under my right rib cage. The pain escalated quickly too where I was unable to hold still. No position brought relief and if I stood up I would get dizzy. I became very hot and started to sweat. After 2 hours I threw up and again an hour later and once more a few minutes after that. The smell was foul. I spent hours in the shower trying to cool off and get relief from the pain. After a little over 4 hours of extreme pain, it let up too where I could hold still. The pain never completely went away just bearable. I was exhausted so I slept for a few hours. Later that day I tried to eat some soup and drink some water. A few hours later the pain increased again but not out of control. It feals like the food isn t going any where and if I lay on my back it s hard to breathe. When I roll from side to side I feal movement and its painful. Help
