Burning pain

I have pain that's like a burning/itching feeling under my skin. It's in one very specific spot on my left ribcage kind of near the side of my boob. There's no lumps in my breast, or any marks I can see but it's bad enough that it's woken me up and I can't get back to sleep. It almost feels like something has really pinched me there, I felt it earlier today on and off like "pangs" but now it's constant and I can't sleep, nothing helps. I'm just venting because it's making me really nervous and I can't do anything about it besides book an "over the phone" appointment with my doctor.
