I have finally been officially diagnosed with IBS. Upper GI was normal, stool sample was normal(no blood), ultrasound also normal. My blood tests showed elevated white blood cells and sed rate. The white cells finally went down to normal, but the sed rate went up even more(from 37 to 45). The Dr. said to call him if things got worse or could no longer be controlled with Immodium and calcium. At that point I should consider a colonoscopy. My question is Do you think that my Dr. is treating me aggressivly enough? How high of a sed rate is too high? How important is the sed rate and what does it indicate? Should I feel content with this diagnosis? I would appreciate any advice or suggestions anyone has.
