This may sound really stupid, but could one be suffering from trismus and not have a full appreciation of it? I have always felt like I was opening my mouth fairly wide, but have this constant "knotted" feeling in my jaw joints on both sides (as well as the stiffness/numbness from the combo of ND and rad). I came across the "three finger" test for trismus, and was surprised that I could barely get 2 between my teeth. My inquiry started because of these awful spasms I will periodically get when I yawn. One yesterday almost took me to my knees.

Am I goofy, or could I have some trismus going on? (OK, even if I have some trismus, doesn't necessarily mean that I am not goofy anyway) Thanks!
