Worst for me was glazing, sliced my hand open. Looked at the blood, thought about it for a few seconds then went to the bathroom and washed it with disinfectant ( thank you for the Cetrimide, it does not sting, must just buy more soon, only got Dettol left and that is painful) and put a gauze pad on it with a lot of tape to apply pressure. Then took 2 painkillers, still was numb, but knew that would not last too long. Then went and finished the window, and walked over to my now late neighbour, who was a registered nurse, and asked her expert opinion. After the obligate tongue lashing, she told me to toddle off to the doctor and get the thing stitched up.
Drive to the doctor, arrive 1PM, and walk in, and there is my regular doctor, just finishing his last patient. He greets me, tells me I am an idiot, and asks how I feel otherwise, and to come through to the treatment room to have some habedashery done to me. 4 stitches later, self dissolving, and a painful shot of Lidocaine ( that does hurt, from a lot of experience of it, and it is hard to do it painlessly, only the paediatricians seem to learn the knack of doing it, though I knew of some nurses that could as well) to prepare for them, and a good slathering of Betadine and a bandage, and I drove back home, going via the hospital to visit. Came home, second coat of sealer on the window, then took the lovely painkillers and met Morpheus for the afternoon.
Before that was just cutting into the bone of my hand with a cutter blade, just taped it up and let it heal, took about a week, and the odd toenail removal. Did drop a drill, pointy end first, and it was stopped by my foot, and went all the way through.
