I'm still at a loss as to how I hurt it. I walked into a door about four weeks ago, and got a decent sized bruise. The tingling and the pain started a few days later. But where it's pinched isn't where I hit it...

Anyways, I'm probably stuck with the pad that I have, since while I am an adult, I still live with my parents and they're paying for all of it, so I don't think they'd go out and buy another one. But thank you for your help!
