Hi dr I am taking serious precautions in consuming anything which could cause coughing. I feel no problem for 2 3 days...suddenly in a day i start coughing and it again last in a day or by next day...this cycle keeps on going..experiencing this problem since 3 months...have already taken all medicine course by a chest specialist even. Pl suggest what could be to the reason for the same...for past 2.5 months i have not taken anything chilled stuff or deep fried or pickle,etc items. Can this be due some item from household only which is creating this problem. Pl suggest
