Today's date is 10/28/11. I read your question and the doctor's answer to your question. I am not a doctor, but I have your symptoms of yellowish brown stools since 2006 and pain in my right side where my liver is located. Before my stools turned this color, I had all the symptoms of hepatitis. I read that the yellowish color can be from the hepatitis virus preventing the liver from absorbing excess bile which turns the stools yellowish brown most of the time, but can occasionally cause greenish stools because before bile is released into the digestive tract, its color is green.
