I'm sorry to hear this, stillin!
I can relate totally with your situation, which closely resembles mine.
Yes, a few days off, a few days off . . . We may feel recovered during that moment of respite, but back at the hard work we both must do, the increasing lack of mobility and resultant pain are exasperating. I hope you can find some level of balance, stillin!
Seems we'll be working till that last moment. ???
Peace.
