Your symptoms sound A LOT like what mine were a few months ago. Have you had a chest x-ray? Because I went to the ER when it happened to me and they found that my lung had collapsed. After the intial collapse of the lung (and before my surgery) I only had a little pain, more like heaviness, in my chest. Your suppose to be short of breath as a symptom, but i was never out of breath and my oxygen levels were all normal cause my remaining lung was doing all the work for me.
