Re: Can penicillin cause a bladder infection?
It is possible that your bladder infection never completely went away. The cranberry juice is excellent at getting rid of the symptoms, but may not clear up the actual infection, so whenever you get a bladder infection you should see the doctor. Also, antibiotics can cause discomfort too because they kill off the good bacteria as well as the bad, so it may not actually be a bladder infection. It is wise to see your doctor.
