Clindamycin
"given Clindamycin  after infected tooth pulled. on day 5 of 7 ,300 mg every 8 hours. I have IBS and diverticulosis anyway, but do seem to be having more diarrhea.  last night I thought I was going to die, not really , but I almost wished I would. First of all my whole digestive track felt very irritated.. my jaw, ear , throat and whole right side of my face was hurting worse than it did before.  managed to sleep for awhile but awoke with that side of my face feeling like it was on fire. No fever though. I put an ice pack on it .I felt fine this morning. To me it seemed like all the infection came to a head and must have drained or something . IF ANYONE HAS BAD DIARRHEA DON'T FOOL AROUND SEE DR ASAP  it could be C DIF and can be fatal !"
