Question

It hurts now when i breathe not all the time though, on my right side boob and it goes to my back. well not that much pain in my back but in my breast. no lumps nothing.. nothing at all. what is this? is it bad?

Answer 1

I get that as part of my anxiety.  It usually starts in my breast and moves up to my collar bone.  It seems to be worse when I have PMS.
