I was diagnosed with pulmonary fibrosis 2 years ago after a lung biposy... i was on prednisone for a couple of months.. but i stopped.. from now on im only using an inhaler (symbicort) but every morning as soon as i open my eyes, my cough starts... and it keeps going for more less 20 minutes.. no matter what i do it wont stop.. after those 20 minutes of coughing im just exhausted... i was wondering if there is anything that could help with my cough and the sputum

Summarized question: What could cause pulmonary fibrosis?
