I spent four and a half days last week with my middle finger on my left hand either in a stiff brace or taped together with a neighboring finger.
I'm not sure what happened, but I was at work Monday, typing, and I noticed my middle finger hurt every time it hit a key and then I noticed it had turned purple. The more I typed the more it turned purple and then it turned numb.
That's not normal, I thought, and then ignored it. I'm a firm believer in la la land. Ignore things and they'll go away. Probably. Maybe, if I hope really, really long and hard enough.
