Welcome to just answer
What does your pulmonologist say about this?
All he knows is that he has not found any infection other than an indication of lung inflamation.
Well in this case I would suggest you go ahead and have a brochoscopy done and if possible a biopsy
I dont think there is a need for a surgical intervention at his point
A bronchoscopy and biopsy have both been done and analyzed. No infection or cancer has been found.
Do you have bronchospasm on clinical examination?
I am not sure what that means.
Well in the absence of infection and cancer in the lungs, other causes of dry cough include constriction of the your bronchi's as in asthma
This is known as bronchospasm
An asthma test was done and there is definitely no asthma
Well I would suggest you get Lung function tests done on a spirometer
That has also been done with no conclusive diagnosis
Do you have stomach acidity problems?
Any history of water brush?
some acid reflux treated with Prolosec from time to time
Well then that should be treated effectively and seen whether your cough settles or not since reflux is a common cause of dry cough
Do you have any further questions?
Could the acid reflux cause the lung inflammation?
Yes it does, a phenomenon known as reflux pneumonitis
