Hope your urinary tract infection
Some of the antibiotics that are used can cause either
as a side effect. Ampicillin
more diarrhea and the Floxacin types can do either. I think
since you were constipated , I think you might have a little
of the stool in the rectum. I would advice that you
try taking a plain fleet enema and see if this clears.
Seapage around an impacted stool is seen often.
Bu t if the diarrhea becomes worse, you may have to stop the
antibiotic and discuss with your doctor. We have to think about
another antibiotic induced colitis called C.Difficile colitis.
Wish you well.
