I cut the inside of my finger on a piece of smooth metal foil, but felt nothing. The first I realised I had done it was when I started leaving patches of blood on things. The cut was quite deep and took a while to staunch, so why was it completely painless? I鈥檝e had similar cuts on sharp objects before and mostly they鈥檝e been very painful, but every so often some cuts don鈥檛 seem to hurt at all.
