Back Pain, Chest Pain & Yawning: Possible Causes & What To Do

Question
Yesterday out of the blue I started experiencing back pain. Didn't feel like surface typical muscle pain but more internal. Then I noticed that when I would try to take a deep breath the pain would travel from my back through to the front in my chest. Then I began yawning a lot but couldn't complete the yawn and again would have the chest pain.
I haven't done anything strenuous to cause muscle pain, I pretty much took it easy and sat around all day. Today its the same thing. Oh and its all on the right side and it feels kinda stiff.

Any idea what is causing it, should I go to the doctor?
Thanks

Hi Rae,
Back pain can be from any number of things. The yawning seems to suggest anxiety. You may simply have some muscle tension of the inner muscles around the spine or rib cage. I would see your doctor if things don't get better by themselves in a couple of days.
