I pushed my hand to the limit this weekend.
I picked up a DSLR for the first time since the accident.
Today I hurt, from the fingertips to the wrist.
But it's from strenuous exercise, not the surgery.
I ended up using a stick-on heat pad to combat the rain and wind, because there's only one artery feeding the hand, not two. I'm sensitive to the cold (not a good thing at Silverstone) and the little but constant heat did the trick.

Thanks Mark!
