I have recently been diagnosed with Fibrosing Non- Specific Interstitial Pneumonia. Also have a terrific cough and occasionally will cough up a tiny amount of white firm mucus. I developed this cough after foot surgery. Ran a low temperature for 2 days. The cough is really chronic and very irritating. I have had it for 5 months. It is a bronchial cough. The doctor doesn't seem to take it serious. I get so very exhausted. Not sure what to do.
