many times i get this feeling when i breathe in which i can only describe as a painful expanding of my lungs. it feels as though the spongey tissue is separating, which i'm sure it is, but quite painfully.
i liken the feeling to the sensation one gets when running very hard and then attempting to catch one's breath (i am speaking of running for at least a mile). that feeling that accompanies the "out-of-breath" sensation is very much comparable to what i feel, only without feeling the shortness of breath. does this make sense?
anyways, lately i have also been experiencing moderate chest pain, although i would rate it more as a discomfort than pain.
i do not believe this pain to be related to my heart, which is what i've heard most.
oh yeah, i'm 25, recently stopped smoking (month ago or more - not a heavy smoker when i did smoke anyways), drink moderately, practice hatha yoga, and am reasonably out of shape.
thanks in advance for all your help.
