Perhaps now is the time to practice playing the one-finger chords with your right hand, and see if you can use the left a bit more than you used to...?

It feels a little awkward at first, but it's amazing how quick it comes....

And, of course my hopes go out to you for a full recovery, but if things don't improve, take a listen to (and read about the full back story of) Ravel's Piano Concerto for Left Hand. It is inspiring, and hopefully helps you realize there's more to making music than our physical bodies....

All the best......
