Hi there, that sounds like an Oxymoron sorta dont it??? Well the only explanation is he may NOT have biopsied in an exact place to determine results to come back inflammed. You don't have to bleed in order to have this disease, I dont. My sister bleeds and no pain so even in families it differs. The disease is very unpredictable and plays hide and seek..damn critters. I have ulcers and inflammation too, and took a few colonoscopies to find it, and yes many times my blood work came back normal... Sorry I dont have answers you want to hear but hopefully your daughter is seeing a top notch Gi, internists are not equal to GI's. You may have to get a second opinion. Where she is inflammed is hard to reach too. Keep us informed ok? Hugs to you too, scary when your child is ill...
