Hello, for the past couple of days i have been having a touch of somewhat painful Diarrhea. I have been taking some Pepto-bismol to try to help with it, but it isn't really doing anything. my Stool has been charning color over these days also, brow to green, green to black, black to orange, and not its a bight color of red. I have not been eating anything red, infact I have not eaten anything in about 2 days. the only red thing that i have had to eat/drink taht was red was some red powerade, and that was about 1-2 hours before my stool ended up being red. Please reply!
