Thanks Dr. I can see like a couple of small white dots on the gum that I am supposing are the bony projections. I sure feels like bone to me (very hard); that is trying to get through the gum. I believe that I am going to make an appointment with an oral surgeon and see what he says. I hope that it is something benign or an old root--although that is my underlying worry that it is something else.
About a week before this happened, I had the dentist that I went to repair a molar on the other side of my mouth that had been badly chipped. After that procedure was when I had the pain from opposite side of my mouth and the bump back there. I thought that maybe when they did the crown/repair on the other side of my mouth, they hurt that side of my gum. I recall they put something hard in my mouth to keep my tongue over to one side, and I worried that the technician assisting the dentist had held something a little too hard against the gum. To be honest, I don't recall whether I had a bump there or not. I do know that it didn't hurt there before the procedure however, and I did not have the pressure in my ear or the pressure swallowing on the side either. I had pain in the side of my tongue a lot but that has subsided thankfully, now it's more of a itchiness/pressure in the ear and the left side of my throat pressure.
