Hello, i am 34 years old, Male, (Never Married), (Never Smoke), (Never Drink) - i am having this severe cough problem since 2010/2011, every year i caught up by this severe cough sometime seasonal allergies (September to March) And sometime non-seasonal, at the start, from 2010 to 2015 i did not notice about it and i never went to any doctor to treat it, i thought it was a normal cough and when ever the cough caught me , it went away by its own, after 2/3/4 months of severe DRY cough.
