Every 2-3 years I get a chronic cough, usually after a cold or allergy event. Everything else clears up, but the cough remains for months. What can be done? Im undergoing radiation therapy and the cough is making me so tired. I DO NOT cough at night, or if I am silent. It only happens when I talk, laugh, etc.
Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you are mostly having allergic bronchitis. Allergic inflammation causes Airway edema and irritation. This causes coughing on activities like laughing, talking etc. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. PUT (pulmonary function test). PFT will not only diagnose bronchitis, but it will also tell you about severity of the disease. Treatment consists of inhaled bronchodilator and inhaled corticosteroids (ICS). Oral combination of antihistamine (levocetrizine or fexofenadine) and anti-allergic (montelukast) Chat Doctor.  Don't worry, consult pulmonologist, discuss all these, and you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
