This is an embarrassing problem but I need to know if I should go to the doctor. Just before I have to go to the bathroom I have abdominal pain and it continues after I’m done for a while. It hurts really bad. Most of the time my stool is different colors and I have seen blood in the stool. Most of the time it seems like an upset stomach but it has been going on for a few months. I’ve tried taking Fiber tablets and drinking more water to see if it helps but it hasn’t. Do I need to go to the Doctor?
