please help!!!!!

peja
okay so the past 4 days ive woke up with a really bad pain in my back and my stomach felt really uneasy like i was going to throw up, normally withthe back pain i could take some pain reliever and it would go away but the stomach pain stayed. the back pains gone now but my stomach still feels like the same. i dont think its food poisioning because i wouldve thrown up already but i honestly have no idea whats wrong with me, ive tried sleeping it of but it comes back and the only time i dont feel the pain is when im totally asleep. i know its not because of my period because im on birthcontrol so i expect when my period is, ive been drinking watet and ive tried to eat as much food as a i can without making my stomach feel worse. someone please help im so tired of feeling like this
