I sent a big ass drill into my hand once as well. I drilled bone even.
Here are pics just after the surgery. "Leave that bandage on for 2 weeks!"
"ok... GO FUCK YOURSELF!" I just had to get pics for you guys.
Did you sever the digitial nerve? I did that's why I had microsurgery to repair that shit.. it didn't work. I still don't have feeling on those two fingers, but it's only numb on the inside halves. It's fuckin bizarre. At the top of knuckle I have all feeling, 1 cm away (towards the inside of the finger), and it goes completely numb.
