You stated that you were treated for some infection with
few weeks ago. Now you are experiencing
change in the consistency of your stool.
There is a bacteria called "Clostridium Difficile" that
produces toxins and causes diarrhea
and even bleeding.
This can happen with different antibiotics and especially
Clindamycin. C.diff colitis
can be quite serious with
complications including toxic dilatation and perforation
of the colon
You have to have your stool tested for C.Diff toxin A&B.
If it is positive you need a different antibiotic.
Please follo through with your doctor.
Wish you well.
