Iv'e had diarrhea for the past 4 days. Two days ago I felt sore in my anal from going to the bathroom so much. The next time that I went to the bathroom (diarrhea) it hurt. When I got up from the toilet, I noticed the water was light red. Then I checked the toilet paper after wiping. It had wet stool with a light color of red bloody mucus. since then every time I go diarrhea its stool with bloody mucus. What could be wrong with me? I thought that maybe it could be that I ate too much soy. The day before I got diarrhea i ate a box of granola bars that contain soybeans. But now after see the blood mucus, I don't know what it is. What do you think?
