It was like a very deep breath that brought on a sharp
to the lower left part of my chest
. Now I want to make clear that at that time I was very raspy and even coughing up phlegm. I had a cough, and I was even told I looked sickly. After my hospital stay, the rasping, and rough breathing stopped. I felt better, and like a moron I didn't quit smoking. Anyways, this involuntary deep breath that disrupts normal breathing patterns followed by a sharp stabbing pain continued.
