I have a slight abdominal pain and diahhrea that is a yellowish brown color but won't go away what's wrong?!?

Time to see doctor: It's impossible to give advice based on your limited information--what have u tried, where does it hurt, what are the accompanying symptoms? Persistent abdominal discomfort can originate from the large ;/or small intestine, stomach, gallbladder, pancreas, liver, female organs, muscles or hernia of the abdominal wall, bladder, etc. You needs examination & testing. Go see the doctor please.
