Hi Jim, I tought I would share with you what happened to me (twice). This is not meant to freak you out but to offer something to ask your doctor about...I teach Anatomy and Physiology so I may be able to offer some "crack-head" advise...4 years ago I was getting ready for work and all of a sudden I felt this sharp intense pain in my upper left chest. I laid down for a minute and I could hear a "click" everytime my heart beat. I thought maybe I tore a heart valve..I went to the ER and they determined that my lung had collapsed spontaneously. It is a called a spontaneous pneumothorax. It was caused by a "bleb" which is like a grape like bubble that grows on your alveoli (air sac). Mine ruptured open and the air I breathed in would go into my pleural cavity (space the lung is in) pushing my lung down away from its lining causing some fucking major pain. They said it was common amoung young, skinny, tall, males. The cat scan will show blebs so maybe mention this to your doctor...the good thing is that they are not cancerous and if you find them, the doctor can do something for you before your lung collapses. When this happened to me I knew NOTHING...that was the scary part..I hope this helps and hope all goes well for you...peace, PJ
