That's what I thought. I'd bet the combination of lymph nodes being removed and the radiation treatments have combined to cause much of the problem.
I haven't found anything so far that really makes a difference. The massage helps, but doesn't eliminate the problem. I have been offered a variety of steriods, etc. that may help as well, but I just don't want more medications.
I really hope the Doctors can come up with a solution for your Dad. He's had a really rough time with all of this.
