Welll...
I did the "not much of anything" for a couple of months in 03- just because I barely could do anything at all
- but in the long run I think it was a good thing for me. Plus I was lucky to get some decent PT persons during that acute phase.
So maybe your PT is on the right track.

Sharon Butler recommends a similar plan for RSI/TOS.
rest
very gentle stretches {per her book or website program}
do only what is necessary for daily activities & personal care
rest after doing activities to offset that usage
-of course
drink lots of water
relaxation
proper breathing

If you follow the plan and put the time in now -you may come out much better off. I know you may get stir crazy or cabin fever LOL.
I got a subscription to Netflix and watched lots of movies, since I couldn't even hold a book anyway.
