Help! Is my new lesser ball python sick?

Hello. We just pick up a new lesser ball at the repticon expo yesterday. She looked and acted very healthy at the expo. Today we checked on her to see how she was doing in her new set up and noticed boogers on her nose/nostrils area.
She isn't acting as if she has a respiratory infection. However we are quite worried, since we don't know what's wrong. I haven't figured out how to add a picture yet. Once I do, we hope someone can help us out and let us know what's going on it would be greatly appreciated! Thank you!

Here is the picture of her nose. You can kinda see the darker booger-y looking stuff on her nose.
It's also possible we are overreacting. But any bit of advice will help! Thanks again! [IMG]http://i42.photobucket.com/albums/e3...ps4074d4b3.jpg[/IMG]

I can't see anything on her nose?

But that looks like it might be a bit of retained shed over the heat pits?

or she could just have been rubbing it in dirty substrate?

Yeah, it seems you might have mistaken the heat pits for nose holes (or the pic is too dark to see). The nose hole are on top, and I'm in agreeance with dr del that it looks like retained shed.
