This is a serious question ; I am on an antibiotic called clindamyacin; for those of you who know its pretty potent and has some poteltial nasty side effects; I was very sick with a surprise abcess on my chin that welled my face up like i had eggs in my mouth, so I am grateful for it as after 4 days there’s hardly a trace of the nasty infection.
However I’ve had the runs all day fairly frequently and its sore in that area now.
I am this close to taking an immodium or something. The instructions on the paper said mild diarrhea is a known side effect but moderate to severe is different as the medication is known to cause ulcerative colitis while on it or even after taking it.

So, what’s the actual difference clinically between mild and moderate to severe diarrhea?
