I have managed to injure the pointer finger on my left hand. I knit continental style, and when purling the pattern into my brothers second sock, I have (repeatedly) gouged under my fingernail with my working needle (a mere size 1) and have actually managed to pull the fingernail away from the skin. It is red and swollen and there is a bit of blood under the nail. I am scared to knit the socks again for fear that I will repeat my same mistake. My husband has suggested bandaging it, which may work, but could encumber my knitting. I considered a thimble, but know that will have grave gauge consequences (if I could even keep it on.) I have never, until now, considered becoming a combination knitter. Maybe I will read up on it (though I am nervous about changing styles in the midst of a project for fear my gauge will change drastically.
I hope it manages to stop throbbing soon, and also hope that the swelling goes down. Thankfully, I won't be knitting anything else on teeny weeny needles before Christmas. That, in and of itself, is a Christmas miracle.
