So...this is a bit gross so you are warned! My Christmas story, for quite a few years I've had scar tissue on the left side of my jawbone, it is a lump of it and really annoying. I have asked civilian and military medical staff about it as it gets sore and been told nothing can do, it is just scar tissue (I have plenty of other scar tissue and it is unlike this). Last night it was sore again, so I decided to operate! so with a pair of nail scissors I got stuck in, out came two large slivers of bone, and also dug further and popped a cyst or something and loads of gross stuff came out and the large "scar lump" has gone.
