white bump on GCC nostril

My 5 1/2 month old green cheek conure, Daenerys, has developed a small white bump right on the edge of her nostril opening over the last couple weeks. She scratches at it very occasionally and is also going through a molt right now. Other than this, she's acting normally, eating normally, preening normally, pooping normally, sleeping and resting normally, etc. No odd behaviors at all. Just as feisty and curious as usual.

I couldn't get her to hold still for the picture (she likes to attack the camera) but the bump is smooth, white, and about the same diameter as the nostril itself.

Is this something I should be concerned about?
