Lee, Tim's right about the jaw issues. I have had a rough time with it as well. I have a close relative who is an oral surgeon, and he made me an acrylic wedge for stretching the jaw muscles. I have also had great success with massage therapy to ease some of the trismus.

After my radiation ended last fall, I was barely able to put one finger between my teeth. After three massages on my jaw, neck, shoulder and upper back, that increased by over 100%.

Even with the improvement, it still gets really stiff if I don't exercise it regularly. The Therabite system works well, but it is several hundred dollars, and I think the tongue depressors or a wedge work equally well, and certainly cost a lot less.
