Hi- Looking for opinions, please.

Over the past year - 1 rootcanal and 1 extraction- (same tooth)

(Had extraction early November 2013)

Now- huge lump on side of lower jaw where tooth was removed. not painful, but it is uncomfortable. It's hard when I touch my face and there is some obvious facial swelling.

I don't see, feel, or taste anything different.

After reading all these posts, it sounds like it's an infected jaw.

thoughts?
