Tan colored stools and diarrhea for 6 weeks. I have been on Vicoden for 5 months until the last 2 weeks due to cutting off 2 fingers, so also a couple of antiobitics during that time. Cipro and Amox. What I have had done: metabolic panel, so ALP, ALT, AST, Lytes, Glucose, BUN, GFR, CBC, food allergy testing, H Pylori, C Difficile toxins, O&P ( X2 - 2 weeks apart, Giardia Elisa, Stool culture X2 , 2 weeks apart - all normal. Then a normal CT scan just completed. I am craving dairy and fat - and I am usually on a low fat diet, fish, vegetables etc. So I have an appt on Monday but I am at a loss. Questions; Would the CT scan show a gall bladder obstruction? Am I missing something? Something in the liver that the enzymes are not showing nor the CT scan? Thanks I would like an opinion on what I am maybe not seeing before I go to the Doctor's.
