For 5 years I've had pains in my ribs, they come and go not very frequently. Should I talk to my doctor?

It first started when I was a freshman in high school. I'm 19 years old now.

It basically feels like I have horrible cramps in the muscles between my ribs. Massaging doesn't help, only bruises. Breathing normally hurts, a lot.

But then the cramps will go away and it's like it never happened in the first place. No leftover soreness, like when I get a charlie horse. I currently have this cramp as I'm typing this question. I was wondering if I should call my family doctor to get this checked out, if it's serious enough.

Usually when it happens, I think it's because of whatever bra I'm wearing, so I unhook it. It relieves some pain, but not enough to make it stop hurting to breathe. So, I've ruled out the idea of it being a bra that causes this cramp, as I wear one every day and if it was the bra it would be happening every day.

If anyone else could offer up explanations or advice it would be much appreciated
