I have it in both hands, but I am due to have my left(fretting) hand operated on Nov 8th. Anyone have any idea about how it will affect my guitar playing? (Yes, It might even improve-needs to)

How long before I might be able to start playing again? How long before I see improvement if at all?

Anything I should avoid, or do while it gets better?

Any comments please.

Cheers.

Eric
