Had lower left wisdom tooth removed 8 months ago, as soon as swelling went down there was a hard bony lump on lateral jawbone about the size of half a marble. It doesn't move and is tender to touch. Certain facial movements or expressions cause a sharp pull and pain is quite bareable. It was knocked 2 months ago and for 2 weeks after, could not open mouth or sleep on affected side. CT shows no osteomyelitis or bone lump, there is a lump in the tissue but not the muscle.
