I am a 37 year old woman.  I am a smoker (just started again about 6 weeks ago after quitting for 6 months).  I have had some awful pains in my left side rib/lung area.  I am fine when I first wake up in the morning but once I get up and start moving around I start coughing (not a whole lot) and the pain starts and lasts all day.  I am a little short of breath and have some discomfort in my chest sometimes but my main concern is the pain in my side.  Can anyone make a suggestion on what it might me?
