Hi K. I don't know if you can answer this but I thought I'd ask ,since no one seems to know. I have had to colonoscopies with two different GI's since January. The first diagnosed mild Crohn's Colitis. The second said that it appeared to be early mild Crohn's, however when the biopsies came back negative he said it must just be IBS. I have had an elevated sed rate for almost a year, sometimes as high as 75, and my C reactive ptotein is at 19 currently. I am afraid I do have Crohn's but the doc says without real evidence( positive biopsy) then he won't label me. Do you know if the positive biopsy is neccessary for diagnosis? What should I do? I saw the pics from the colonoscopy. There appears to be inflammation and sores in the rectum, sigmoid, and illeum. Now the doc is saying it must just be lymphoid follicles. I am so confused. Do you have any advice/ suggestions?
