Hi A.! My daughter did this for awhile, and I thought about taking her in, however, there isn't anything the dr. can do as far as medicine goes. I bought one of those vapor plug ins by PediaCare, I swear by that - it cleared her up in 2 days! Secondly, for the acne, its probably irritated from the constant drip, before bed, put a little vasoline under her nose, and that should go away too. You don't want to give her any meds, as they are not safe and do not work anyway.
I was actually proud of myself for "curing" this on my own, usually I jump and take the kids to the dr. only to find that they can't do anything for the cold! Good luck!
