Over the last 3 months, I've gone through having severe stomach pain, nausea, constipation, diarrhea, a non stop fever, mucus and blood in stool, and I lost close to 20 pounds in the first month. My first doctor told me that it couldn't be IBS because IBS doesn't cause fevers, so he gives me some medicine and sends me off. The medicine didn't work, and so he referred me to a specialist. The specialist did a CT scan, Colonoscopy, and Endoscopy both with taking biopsies. After the Colonoscopy and Endoscopy, he mentions to my parents (I'm only 17 so everything went through my parents) that he thinks I could have Ulcerative Colitis because he found 4 ulcers in my colon but he'd have to wait for the biopsies to come back. So a week later, I go to my checkup, and he says that he doesn't have enough evidence to prove its IBD, so he diagnosed me with GERD, IBS, a food allergy (doesn't even know which foods) and other "stress related stomach issues. " So he gave me medicine for the GERD even though I don't have symptoms of that, and it hasn't helped at all. I'm still in pain, still have the other symptoms I listed off above. All of this has really affected my life. Completely messed up school for me, and so my question is, is it possible that I have IBD? None of this adds up to me, and nothing he's told me to do that'll help has helped, so I feel like something is missing.
