It's hard to not be able to use your hands. Do something that you wouldn't do otherwise:

Learn a new language
plan a garden
read a bunch of books
learn to sing
visit some people who don't often get visitors
plan a post-recovery trip to somewhere you've never been before. Get the guidebooks and make an itinerary
go to the library and browse the shelves
read to a kid, or have one read to you

Consider this time as an opportunity for something different.
