I got my wisdom teeth pulled about a month ago. The swelling went down and I was back to normal after a week. I had class earlier today and everything was fine. Then an hour later after I got back from class, the right side of my face was really swollen, in the same place as it was when I had my widsom teeth pulled out. I had not hit the area, had any pain eating, or any other sign that swelling might occur. Seriously, the right side of my face swelled up really bad in about an hours time. Anyone have any ideas? I took all my infection meds even after the pain was gone after I had my widsom teeth pulled out so I dont think it could be an infection that wasnt wiped out from my surgery.

Thanks
