Speaking of which. I'm having a problem with my left nipple.

My cat jumped on my chest and sliced it open a couple months ago. Since then, while waiting for it to heal, I've been scratching at it and rubbing it and stuff. The welt's gone at this point, but the swelling hasn't gone down and every time my shirt rubs against it I get slithery feelings that go down south. I think I woke up the nerves.

What do I do. If I keep it from being bothered will the nerves go back to sleep eventually?
