@laura34 I wanted to add that I used to complain that my lungs burned all of time. My dr said there is no nerve endings in the lungs, therefore it wasn't them that was burning. The burning sensation turned out to be acid reflux. It was my esophagus and maybe part of my bronchial tree that burned from acid erosion. Once I treated that and made lifestyle changes; it went away. You having been exposed to burn pits may very well have damage from that. That was a great tip from Terri aka @tdrell about NJH having a special dept for service people.
