Hi. I understand your concern s. Try steam inhalation and warm salt water gargling thrice a day for three days. If it does not settle then consult a pulmonologist via teleconsult

Hello from your history and background of allergy, the post nasal drip is probably causing the cough, if you have acidity, this problem could be increased by it. Steam inhalation twice daily should help, also try finishing your food a couple of hrs before lying down at night and avoiding spicy food.

looks like you are suffering since your teen age,history wise it looks like bronchial asthma with sinusotis. get yourself evaluated with a pulmonologist asap. need to have a pft and few other tests.

Hi.. I understand your problems.. From the history you provided, you could probably be having cough due to post-nasal drip.. Do you have associated fever / sore throat / body pain? If not, try steam inhalation, salt water gargling, avoid spicy / oily food.. Antihistamines and cough suppressant are available over-the-counter. Consult a Pulmonologist if symptoms don’t improve.
