I have had both wrists done and the relief is fantastic and very WELL worth the operation the pain has never returned, ever, so don't worry about it you you will not be bothered by the operation I had one done under general anesthetic and the other by local anesthetic, I had no feeling at all during both so it is not a problem believe me.
As for the bird side of things, well they will only do one op at a time and the time between them is months so hide the bandage if you are worried about it.
Ben was not here when had my done but I am sure they will be OK, just like everything else give them time.
Hope this helps.
Bernie.
