Hi,
I'm not sure if this is the problem, but a have a friend that had the same thing and it was diagnosed as sinus congestion. The dr felt the sinus was draining down and into a pocket it had found or made. Nothing to be done. She has learned to live with it and will use sinus meds when it bothers her too much.
Just a thought. Hope it helps!
My best to you,

don't know. I currently have the same thing. I get it on and off a lot too. I couldn't sleep with the pain of it this time. I read on one website that it could be an allergic reaction. brushing/flossing and rinsing with mouthwash helps. I was probably a little late to do the mouth was. I think it got up through my gums. The post just suggested waiting for it to pass...
Seeing an oral surgeon is advised.
