I'm taking clindamycin for an abscessed tooth and it's now day 6. I'm still having episodes of pretty bad pain usually after I eat although I'm very careful. Sometimes it doesn't hurt at all for a few hours but I still have to take Advil a couple of times a day. The root canal is scheduled for 2 1/2 weeks away and they just won't do it any sooner. Tomorrow is my last day of antibiotic and I'm concerned that I'm still having pain at intervals. Has anyone else had this?
