Definitely call the piercer and see what they say. I have never heard of this, but I know that when I first got mine done it did run. Try cleaning it out with a salt water solution. Maybe there is something in your nose that is making it irritable?
It could very well be part of the process of healing for you. Everyone is different. Your nose naturally produces mucous to clean out crap.
Soak your nose for a bit in the saline solution, about 5 mins, and do that everyday. Hopefully it will work. But call the piercer to be safe. They might know what is going on.
