I have a lump on my lower jaw that seems either fixed to the jaw bone, or part of it. Its a little sore when I fiddle with it; about the size and shape of half an almond, split down the length. I first noticed it about a month ago, maybe two? And thought nothing of it. However it's come to my attention recently, I can't really say if that's because it's gotten bigger or whether its something mental.

any thoughts would be appreciated!

thanks!
