Not to be overly gross, but after just having surgery on a hemorrhoid that followed a course of action very similar to your finger, I can say two things with certainty:

1. I'm extremely glad I wasn't out in the woods. Especially alone or far away from advanced civilization.

2. Thank God for surgeons.

I don’t know what I would have done. Makes you realize that, no matter how much you prepare, sometimes S**t happens. Or in my case, didn’t happen.
