Rubbing sound/sensation in lower throat/upper chest

[camden73]

For the past four years, I've experienced a strange rubbing sound/sensation in my lower throat/upper chest 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.  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...I used to only hear/feel it when I was rotating vigorously (like when doing aerobic workout), but now I hear/feel it whenever I'm simply doing daily activities and happen to turn or twist at the waist.  
Any thoughts on what this may be, or the cause?  
I have no sore throat or hoarseness or any other throat/esophagus symptoms.  I do have very occasional heartburn that responds easily to Zantac.  
Thank you very much.

I would see a doctor today if possible.

I underwent a chest xray to look into this. It came back normal but it was discovered I had pectus excavatum, which is a fairly common condition that shouldn't cause me any problem but I would be interested to know if anyone else has this and if it is related. I did suffer from pollen allergy this summer but now its colder I can still hear the noise. It does seem to be worse when I have a cough or indigestion so I think there is a link with chest inflamation. Maybe we should try anti-inflamatory drugs? I guess if its not hurting you you should try not to worry though! My doctor did say there's a reason they don't listen to your chest when you're moving afterall!

My doctor has said he thinks it is due to hyper inflation of the lungs which can be caused by allergies, asthma, respiratory stress like colds and flu,  and change of air temp like when your in a nice warm house and walk out into the snow. If you concentrate on expelling all of the air from your lungs then twist it does (for me) seem to lessen.

I think people are describing two different things here. One seems to be more of a wheezing thing whereas what I have and what other people have been describing is more of a bone softly grinding sensation which feels super strange. For me it feels like it comes from my upper spine and comes out my mouth, it doesn't make sense obviously why no one has been able to find out why this happens. I'm on it though!

I have now seen three doctors about this. Chest xray tomorrow. I'm determined to find out what this is.
