Chest pain with popping?

[Radiohead51]

I have had this strange chest pain that worsens with deep breaths and movement. It usually last a couple of minutes before gradually subsiding. Sometimes, if I shift my body right, I feel like something shifted in my upper chest (near the ribcage) quickly, and the pain then goes away. Sometimes I feel this quick shifting or popping sensation when I dont have pain. FTW?
