I am 16 years old and I have been having stomach pain (Awful), blood in stool, sores in my mouth, swollen lips, diarrhea, weight loss and no appetite for the past 6 months. It just keeps getting worse. My mom brought me to a gastro and he did stool samples and blood work but it showed nothing. Oh and by the way my aunt has one of the worse cases of crohn's Hopkins has ever seen and she got it when she was 16 and my two uncles (all on my moms side) have ulcerative colitis. So he decided to do a colonoscopy and an endoscopy which again showed nothing. He diagnosed me with IBS and put me on dicyclomine which doesn't do anything. And the other day I had some sort of scan to check for bleeding I guess.. It was some sort of x-ray thing i'm not sure what it was called. Do you think its possible I could have crohn's because thats where my symptoms point me to but all the tests come back normal.. It's really frustrating and I feel like since they don't have any proof they don't care. Someone help me please.. I just feel like they think i'm a hypochondriac or something..
