two threads about wisdom teeth in the same week
you appear to be in charlotte, nc... assuming you have insurance, go to carolinas medical center emergency room. you could have an abscess (a pocket of pus) in your jaw, or it may just be causing pain and inflammation... either way, you might get a pannorex (xrays of your teeth and jaw), a few labs drawn, some pain medication, and possibly a consult with oral surgery (i'm not sure if there are oral surgeons there or not).
as far as home remedies, it doesn't seem like much is going to be done if you won't/can't chew or touch your cheek. i'd say to use warm compresses on the outside of the jaw 15-20 minutes at a time every hour.
