This went on for three weeks so on August 18 I was referred to a gastro specialist and performed several procedures. Creatinine was normal, SGPT was high (I have fatty
liver), CBC showed all components within normal range. They did colonoscopy and found a mild swelling in the last 6 inches of my colon (doctor wrote "proctitis"), and a slight internal hemorrhoid. Although the doctor said these couldn't have caused the on and off diarrhea.
