DON'T do both hands the same day! You can't use the surgical hand for anything for at least 2 weeks. You do get to wiggle the fingers, but that's all. Most places wouldn't even allow doing both hands the same day!! I'd dump that doc fast.
No, you won't be able to drive if you do this, not for a long time. There's only a couple of stitches in each hand under each finger that's operated. The doc will remove them at the first visit which is 2 weeks out. The stitches are in the joint where the finger goes into the hand. After the stitches are out you still have months of therapy, and it's painful if it's working. Mine was too gentle and I still have pain after well over a year. You HAVE TO work hard on your own to keep scar tissue from tightening up your hand so you can't use it. I didn't find out what I should have been doing until it was too late.
You have a giant piece of foam "swiss cheese" to wear all the time for 2 weeks. You aren't allowed to get the bandages wet. It hurts bad enough you won't want to use the hand anyway.
There's no pain at all to the operation. You don't need anything IV. I asked not to have anything, didn't need it. It's for sissies who are panicked. The local will numb the hand so you don't feel anything until the middle of the night. Have your pain meds handy and take them at the first hint of pain. That goes on for a couple of days.
Don't do both hands at the same time. Wait at least 3 months.
There's lots of info on the net, watch the videos so you can see what you are getting done.
