Lol, are you scarred or scared? Gee whiz, maybe both now. First, IMO, you have no business, taking random drugs from a friend. That is just dangerous and just plain not smart.
Perhaps a trip to the ER? They have to treat you there. And then you should get a definite answer to your symptoms, scarring, and/or or being scared.
Hi,
Antibiotics can cause diarrhea/colitis.
C diff infection is a common complication of antibiotic treatment.
Stool test may be done for confirmation.
If confirmed you may have to take medications for about 14 days.
