What is this?

Guys I have this pimple like thing on my face. I have no idea what it is, it's not a pimple because it never gets a white head so I can pop it it's just like a bump. It goes away and comes back every so often. The bump is by my nose and has grown on both sides but usually is only on one. What is it and how do I get rid of it?!?!?!?
