Cut fingers

[dougie_monty]

A couple of days ago, I cut my left pinkie (I'm right-handed) on a plate that suddenly broke into four pieces as I lifted it out of a sink of soapy water. I started bleeding, and, oddly enough, the area of the pinky near the cut looked depressed, as if something significant had really drained out of it. Since then I've kept a bandage on the pinky, but I want to know: Why would the finger look dented? Is this a natural reaction to the trauma of being cut by a broken dish?
