I am sure most of you know what it feels like when you know a zit is coming in...its painful and feels like its swelling and throbbing...

Well I am getting this pain in my left breast (on the right hand side..so close to the center of my chest). Its been ongoing for a while now and I have ignored it and then it goes away but its getting pretty annoying.

I am 21. Not sure if that is relevant...is it worth getting checked or should I just wait it out and hope it goes away???
