My belly has been bothering me for a couple days now, but I thought at first it was because I had left the country and was just adjusting to normal food again. However, it has been 5 days and I was constipated until 2 days ago now I have diarreah every time I have a bowel movement. Today, after I peeded, there was blood after I wiped. My belly is uncomfortable however nothing else seems off. What could be wrong with me? Should I see a doctor? -A concerned college student.
