All four wisdom teeth have been showing through my gums for a while, but now the one on the lower right side is causing problems. Every time I close my mouth I'm biting the inside of my cheek way back by my jaw. Ther is absolutely no way to prevent it other than pulling my cheek out with my fingers! I have an icky whitish callous sort of thing back there with a sort of "dimple" in the center from this. The surrounding gum is swollen and tender, I seem to have a small knot on my jawline that is not on the other side and most alarming of all I have had a mostly mild but sometimes severe headache since it got really bad. No Exedrin or painkiller will touch it and if it's severe when I go to bed then it's at least moderate when I wake up. I've had this head thing for about 10 days now. I know what I should do, but I'm uninsured and fairly broke. Advice, opinions and sympathy encouraged. I probably don't deserve the sympathy since I'm not doing anything for it.
