I Had Diarrhea For Some Time, Had A Colonoscopy A

I had diarrhea for some time, had a colonoscopy a week ago and was negative.now I am very nauseous, have had two hard bowel movements that was mixed brown and white. I have had a cholecystectomy years ago. My urine is dark. My LFT's were checked 2 weeks ago and were normal but so was my urine. Please help.
