Michael, I had all the numbness you mentioned and today although the feelinging in those areas is a tad less intense than on the other side, if something itches, I scratch and I feel it. Took about six months to get that good, if I remember correctly. There is not an inch of that area that is not sensitive to even light touch. Just about the time you begin to get used to it, and you will, you will notice that it is improving. So don't worry. This, like so many other things, will most likely straighten out with time. As Bellarte so wisely says, patience is the name of this game.
Also, listen to Barb about keeping your mouth open. Do this during rad, after rad, and do it a lot. Nobody told me to do that, and it was a lot of work to get my mouth open wide post rad.
Finally, my smile returned to normal and yours will too.
Good questions. While I know you are extraordinary (grin), in this instance you are absolutely normal.
