This started last spring for me, and the doctor listened to my lungs and even ordered a chest x-ray - everything was fine
of course. I got diagnosed with VDD before christmas, and many
of my
symptoms are the same as yours :) I was at about 13, now I'm up to 56 (!), some symptoms are still with me. Actually most of them, but many are less severe. The strange thing is - the chest-thing was gone for a long time, but now it has come back.
