Hi. Had a wisdom tooth surgically extracted on May 26th. Took 7 days of amoxicillin, 500 mg, 3 times per day. Developed infection in left jaw and Tmj area. Been on clindamycin, 300 mg, four times per day, for ten days now, and while I have noticed improvement, I still have infection and drainage through the incision site into my mouth. Still have pressure in the ear drum tmj area and am starting to feel sinus pressure on left side of face again. I am also feeling tightness in the back of my neck. My clindamycin runs out tomorrow and I am worried that this infection is becoming resistant to treatment. What should I go on to kill this infection?
