I think Janlaton may be talking about costochondritis, which is inflammation in the joints between the ribs and sternum. I have heard of the pain occurring towards the side of the chest, but not in the back. The treatment is, like Janlaton said, a NSAID (non-steroidal anti-inflammatory drug, like Advil or Aleve), and using a heating pad. I am by no means a medical expert (only a lowly medical student), so please make sure you see your doctor if it doesn't go away! If you can describe a little more about the pain though, it might be helpful. For instance, when did it start? And does anything make it better or worse (i.e. exercise? heat/cold? any meds?)? Do you notice it at any particular time of day? And what other tests have you had so far?
