Does staph infection itch?

I was wondering, because I went to my friends and stayed the night with her and she has staph. She is taking medication for it, but me being stupid I slept in the same bed with her (just friends). Well, she said I could only get it if I touched it, so she wore pajama pants. And I don't think her mom would have let me stay and let her have a pool party if it wasn't safe. But I'm paranoid and afraid that I might have it. I got spots on my legs that itch. Now, they might be mosquito bites cause we were outside until 11. But I could have still got it from her, right? She told me it just really hurts.. Mine doesn't hurt, it itches really bad. If I scratch more, and scratch other ares will it spread (if it's staph) I stayed at her house 2 nights ago. So if I did have it, would it be like this already? She said it doesn't itch, but maybe it does before it gets bad? I dunno. I'm just paranoid.. Please help me D;
