I live in delhi. I had cough from around 15 Aug'18. I visited doctor around 25 aug. But his medicines weren't found to be effective. From an x-ray he said I do not have pneumonia or TB and said might be a pollution effect. I moved to Assam around 5 Sept. But I still have cough. What should I do? (No mucus while cough But mucus forming in nose). Thanks.
