First of all, you DO need to go to the Dr. But I wouldn t jump to any conclusions. It s probably GERD (Reflux Disease) which would be exacerbated by the smoking by the way. Reflux doesn t have to be just after eating. My bet is that, whatever it is.. it s probably related to the upper gastro-intestinal track and most likely easily fixed. HOWEVER: GERD that goes without treatment is the leading cause of esophageal cancer, which is deadly and with the smoking, you re at even a higher risk. So, the first thought is still an important one... go see your Doctor ;-) ---- I doubt it s pleurisy... Pleuratic traumas are usually sharper pains and are persistent, not come and go. Also, shortness of breath is also associated with pleurisy.
