I went to the ER,
and was given
clindamycin 150mg x12 a day. After 3 days, it was twice the size it was before,
and very painful. I had an appointment with my doctor, and he took me off the clindamycin, and put me on penicillin. By that night, my jaw was 2 times the size it was that morning. I went to ER, and was told it was an abcess. They admitted me, and gave me iv antibiotics. My jaw kept getting bigger until the ENT came and did a I&D, which provided much needed relief.
