position dependent ronchi while deep inhale

Over 15 months now have consistent and unique symptoms.
While inhaling only and only in the latter part of a deep breath a feeling of ronchi especially on left back side (but sometimes middle part of chest as well).
Also this occurs only when lying on my back or lying on my left side but never when lying chest down or standing stright upward.
Also, after a deep breath when feeling the ronchi sound it sort of clears it for the next 30 seconds or so i.e. a second consecutive immidiate deep breath will not result the sound (only if I wait 30 seconds or so).
Chest x-rays are normal.
Bronchoscopy of the lungs was performed and came out with no findings.
No coughing or other evident signs over a year now.
My specialist doctor does not have an idea and just wants me back in 6 months for a checkup.
Anyone can suggest or give a clue ?????
P.S. This hole thing started after an ilness which involved a lengthy and strong cough period of over a month.
Thanks

I had the same symptoms started after a repiratory illness at the peak of H1N1 season last winter. Symptoms (rubbing, crackly) feeling upon deep inspiration lasted for at least 6 months. I had an extensive workup too. All negative.

For the past 2.5 years, I have had the exact same pattern that you describe... lung crackling on deep breath only while lying down on my back. It also clears up immediately after it crackles and then I have to wait about 30 seconds or so for the crackles to return on deep breath again.

I also do not have it while lying on my chest or standing upright. I've tried to describe this to my doctors but so far, no one has even heard of this particular pattern.  

To make this worse, my doctors "cannot" hear the lung crackles that I describe. You did not mention if your doctors can hear the crackles. They told me that it could be cartildge rubbing againt each other so they wouldn't be able to hear that. But then again, they can't understand why it would only be while lying down on my back. Basically, they have no idea what is going on.

I've seen a cardiologist, pulmonologist, endocrinologist, etc etc. To date, I have no diagnosis.

I would greatly appreciate any insight.

Thank you

Perhaps you have some mucus plugs that just move up and down, but not enough to come up and out.  It may be out of the reach of a bronchoscopy.    Can't think of any exam/test worth the cost to further investigate.  Happening on one side and noticable when laying down might just be pressure from the lung tissue laying over the plugged area pressing down on the area.  Can't think of anything much to do about it but to keep up with fluids - it might loosen it up enough to finally be coughed up higher into the lung tissue and then coughed out.  Or it might just dry up on its own.
