bacterial infection
"I was prescribed Clindamycin in a hospital emergency room for a bacterial infection (cellulitis) in my lower leg and was on it for only about 36 hours (six 300 mg doses).  I experienced a severe headache and began experiencing diarrhea.  I called my doctor and asked for a different medication because I have to work and couldn't while experiencing diarrhea.  My doctor put me on metronidazole (500 mg) 3 times a day.

I've been off of Clindamycin for 11 days today and am still experiencing mild diarrhea, depression, anxiety, and shortness of breath."
