Hi - I haven't written in a while, but was wondering if anyone has experienced this lately. The other day I noticed I had on and off pain on the underside of my left upper arm and then later that day I went to take a deep breath and I could feel a little bit of pain in my upper chest. This also happened when I yawned. I don't know if there is some kind of flu bug going around, but this just really scared me when it happened and just wondered if anybody else has experienced this same thing.

I have that when my muscles are really tense up in that area. I think if it happens consistently and gets worse, that's when you need to see the doc to check your lungs. But as far as the mild, off and on type stuff, I have that every week.
