Thanks for your question on Healthcare Magic.
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. PFT (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) drugs is also beneficial in your case.
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.
