What to Do About a Right Side Maxillary Protrusion/swelling Along with Rigth Side Jaw Pain/swelling?

I hit my right side lower jaw/chin bottom first onto a wooden table on April 2012. My doctor requested i get a xray of facial bones, for anything broken/fractured. The xrays came back fine.My question is if there is nothing fractured/broken, why do i have alot of pain on both my lower jaw (mandible) & upper jaw (maxilla) and on top of that why do i have what seems to be a right side maxillary protrusion/swelling of the right maxilla, along with swellness and pain on the right mandible.
