There's something wrong...

[user]

Hey, I've been getting pretty addicted to Powerballing, and there seems to be a problem. When putting palm towards my face, on the left side of my wrist there's a red spot. This red spot becomes more defined when I powerball, write, or whatever else. I couldn't have possibly broken anything, because it doesn't hurt at all, but that's not normal. Has anybody else experienced this?
