It is very difficult to diagnosis from this forum, but I would want to know if you clench your teeth or if you are a bruxer. I would start with your general dentist and possibly a dentist that specializes in TMJ dysfunction.
Yes, I have been told I have TMJ, but like I said, its not a soreness that I feel, its a pulling sensation, from the back of my tongue, very dry under my tongue, on both sides of my cheeks and down my neck. I feel like it follows my lympnodes, from what I know (little) about them, but everyone says they aren't swollen. I am very sensitive in my cheeks, not my teeth, to cold and sour foods all of a sudden. My general just looks at me, trying to get back in with my dentist and am thinking of also going to an ENT.
