text: what do i do with shots of lung pain? every few weeks i get a very stong shot of pain in the left side of my lower lung or rib cage.. although it feels like it only takes up the size of a pin. what it exactly feels like is a small pin stabs me in the lower left rib cage or lung shoots out the other side of me and then comes back the other end, in about 1 second. what is it ?? it could be pleuracy which can feel like you are having a heart attack.  or it could just be heart burn.  in either case you should see a doc because i, of course, am not a specialist in any medical area.  my only experience with your problem is that my mom thought she was having a heart attack with the same symptoms and you don't want to ignore it.
