I'm pretty sure I have Ibs but I'm still so scared I could possibly have a sv? since Sunday I've had really bad pain in the middle of my stomach and I had bad constipation and had to use miralax and dulcolax. on Tuesday I had d* twice but not very bad, and I've felt very nauseous since the pain started. going thorough my zofran like crazy! I felt okay today until dinner and now the pain is back. I'm pretty sure it's acid and gas but I'm still so afraid to go to school tomorrow. I've also had a swollen throat too so could it be a light virus? please reply
