Aw, Karen--my sympathies!!! Having just gotten out of the huge fingertip to hand cast then splint, I feel your pain.
Don't try driving...it's too dangerous with that huge club-like cast they put you in. I had to be shuttled too/from work while mine was that way.
We have a long weekend coming up. Sit in a cool/shady spot and drink lemonade. Let someone else do whatever needs to be done. Heal quickly, my friend.
