Chest pain from tight bra?

So a week or so ago I wore a really tight bra for a few days (sleeping in it and all) and after I took it off I noticed I had three blue veins on chest. These haven't disappeared. Anyway, I was dancing around in my room earlier today and I felt a pain in the right side of my chest (not a really bad pain, but still). I was walking today earlier and I don't think I felt anything. Does anyone have any idea why the chest pain occurred and is it necessary to get checked out (I really don't want to haha). Tweet
