interesting. (i hope this is interesting to you! :-)was awake for several hours last might and slept fitfully with more discomfort ( had to keep turning to the left)and twinges, aches than I've had before. Also, when I sat (to meditate)yesterday, at 6:00 central time the whole area, if I were to draw a 3-dimensional box around lower right jaw, neck, through to the back of the skull was hurting. Really hurting, for about 20 minutes--8/10, then just stopped.(receded, back to awareness of 'something going on', but without pain) We'll see, today....going to sit again soon.
