Well, if you want to get rid of it your best bet is to chop it right off!
Just kidding. I have suffered this problem myself. The best thing to do is to blow your nose hard and often. That will keep your airways clear. If you feel congested, but blowing your nose doesn’t help, take Mucinex D and use Ocean nasal spray. The Ocean is a simple saltwater spray, so you can use it as often as you like without any rebound effects. I hope you feel better.
