I've been experiencing right sided back and chest pain since Sunday, at first I only noticed the chest pain and then I had back pain which is pretty much directly behind the chest pain. I didnt link them at first but when I do a deep breath it feels like the the painful areas are being pulled together. The pain in my chest feels like its exactly where my breast is but deep down so definitely my in my chest and not breast related. I've googled loads and can't find anything that fits this, I'm thinking I might have pulled a muscle so I've been putting off getting a gp appointment. Any ideas what it is?
