I REALLY smashed my right middle finger just about a year ago. I closed it inside a folding wall in the classroom next to mine. I had a large gash on one side and lots of damage under the nail. It was kind of fun, giving my boss the finger while he bandaged me up. I never did go see the doctor. Thom sterilized a needle and put a few holes in the nail for me to relieve the pressure a couple of times. I just kept an eye out for infection. That would have sent me to the doctor. I lost the nail, ended up ripping it off while putting on my wet suit at tri. And I still have some nerve damage, not surprising since the finger was crushed. I am very careful when I close those walls now.
