I recently bit my lip. At first it wasn t anything too bothersome or uncomfortable but a couple of days ago It swelled up and because very raw. That wasn t even too much of a problem but then I developed a pain in my jaw right behind the lower jaw bone on the right side. there isn t a lump, in fact it feels like the side that hurts is less firm than the side that doesn t hurt at all.. It s uncomfortable to move my head, and hurts bad when i touch it. also, when i move my tongue I can feel pressure in the area but not pain. What is this and should I worry?
