I went to the Dr. yesterday because I caught a bug that has given me diarrhea for the last 5 days straight. He told me to try BRAT, probiotics, water and pedialyte until next week and if I don t get better to go back for tests. This morning I woke up and had 2 almost regular stools. Then again this evening I grew sick again. I again had diarrhea as few times and now I feel as though I need to go and nothing is really coming out; mostly air. Some of the times, with the air, stuff is coming out. Almost a mucasy substance. Now, I see traces of blood in it. Nothing major, a few streaks. Should I worry and go to the er? Wait until tomorrow and go to urgent care or just wait and see if it passes?
