What causes the burning sensation when you have diarrhea? Can farts be acidic too? Both seem diarrhea and flatulence cause a burning sensation on my bottom if I have either for too long.

    Diarrhea can be acidic or not, depending on the cause. Burning sensation on your bottom during diarrhea can be due to acid, spice, salt...Burning does not necessary mean that diarrhea is acidic.
