question: For the past month or so I have noticed that I get very bad chest pains when I lay down in weird angels or if something is pressed on my chest. My girlfriend likes to sleep on my chest and even that slight pressure hurts like hell. Im 16 and im not sure what is wrong with me. My back also tends to hurt a lot and im not sure why. I have told my doctor about this and he said its probably just my muscles. Any advice/ideas?
