I pressed at the base of my neck to the side, just above my shoulder

All I was doing all 3 times was leaning to my left on the couch. So all I can think of is that I am kinking my neck or something.

I have no pain at all so I can't see how it would be teeth related. I am dreading 7:30 tonight. It's always at that time which is simply bizarre. I haven't just eaten or anything like that either. If it does it again tonight I'll go see my dr tomorrow. Very hard to get an appointment on a Sunday
