For the past four years, I've experienced a strange rubbing sound/sensation in my lower throat/upper <span style = 'background-color: #dae8f4'>chest</span>
area. It occurs only whenever I twist my torso from side to side, such as when exercising, or quickly turning to the side via pivoting at the waist. It feels & sounds like something is causing friction. I cannot pinpoint where it is coming from, but it seems to be my lower throat/upper chest
, somewhere around collarbone level. It seems to be located within the windpipe or esophagus.
