How many of the pain meds. have you taken? I'd hold off on putting anything on it just yet, let the antibiotics get into your system like sjb said. Maybe you could call and ask if the Dr. can prescribe some other pain med. if the one your taking isn't working. As far as the abscess, that unfortunately is going to take a few days to calm down. When my husband had an abscessed tooth his Dr. gave him a pain med. to take along with the antibiotic.
Hopefully you get some rest and feel better..JJ..
