What causes non stop coughing and is it treatable?

Brief Answer: It could be asthma or ILD. Detailed Answer: Hello, Thanks for posting your query on XXXXXXX From your description, there are three possibilities in your case: Infection Asthma Iterstitial lung disease(ILD) In my opinion, infection seems unlikely and asthma and ILD need to be excluded. I would like to know the following: Do you have any history of allergy like allergy to smoke and dust etc? Are your symptoms progressive? Any history of joint pains? Bronchiolitis and H1N1 are unlikely as they are acute conditions and won`t linger for so long. In view of x ray description of lt lower lobe tree in bud appearance and lymphnode enlargement, TB infection needs exclusion though it is rare in your part of the globe and the xray finding may suggest ILD as well Having said that i am still inclined to think of asthma and ILD. This is because you say that you feel better with medrol and pulmocort. You need to get a second opinion on your CT chest. If required, A HRCT may have to be done. You should also get a lung function study done. You should consult a pulmonologist in person who can review your case with all the facts and advise you accordingly.

Brief Answer: Reticulonodular opacities are seen in HRCT in ILD. Detailed Answer: In ILD, patient has dry cough and shortness of breath which is normally progressive. In HRCt, there is reticulonodular opacities mostly in lower lung fields and bilateral. There may be other findings depending on stage of disease. In asthma patient has cough and shorness of breath but mostly chest x ray or ct is clear. There may be history of allergy. As suggested, do consult a pulmonologist.
