back hurts due to rib spreading....

Babybear70

So here is my thought. I have had pain on the right side of my spine in that big long muscle that runs along side of your spine, as well as right under my right boob. I'm a pretty short person, with a really short torso and I'm wondering if perhaps the reason all of that hurts so bad all the time and I can get no relief from it is because my rib cage is spreading apart like opening a book. Which in turn puts weird pressure along your spine where they are connected and makes the muscles do all sorts of weird stuff! Sounds right to me....what do you girls think? Is anyone else experiencing this?
