It seems to be located within the windpipe or esophagus. There's no pain, just a friction/rubbing sound and
sensation. The sound is especially audible if I open my mouth while twisting my torso.
Three years ago I saw my Dr about it and she ordered a chest CT scan
, which was clear. My concern is that the scan
began at lung level and didn't cover my lower throat area, and that's where I think this is coming from. I'm also concerned because
since then, it has become much more pronounced...
