Purg,
I hesitate to say I'm happy there may be a cause to all your pain, but for many years I have been more comfortable with knowing enough to build a plan, however weak, than to be completely clueless.
And yes, I agree, radiation just keeps on leaving us little jewels of pain and trouble.
I will say that I am long past my surgeon's "dead by" date, so I deal with what I've been dealt.
Who knew we would still be here!
