I feel for you - and not having been in your shoes.
Keep positive and keep the hands (both) moving as well as the rest of your body.
Your hand is not a disaster!

I would ask how your fall happened. It is how many of our injuries happen (myself included).
It has perplexed me so much that I have a project "on the burner" to address the fall issues. I had a neighbor of a coworker experience a catastrophic injury (broken ankle) and decided "I can do this!" and so I did and I am.

I have officially joined the "Carpal Tunnel" Club. I have my first real steroid injection into my joint this week between PT for my hamstring. Time will tell how it goes.
