Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of post infectious bronchitis is more.
Bronchitis is inflammation of airways and it is common after viral upper
respiratory tract infection (URTI) like cold.
Your symptoms like continuous cough, breathing difficulty etc are also seen in bronchitis.
So
consult pulmonologist and get done clinical examination of respiratory system and PFT (pulmonary function test).
PFT will not only diagnose bronchitis but it will also tell you about severity of the disease.
And treatment of bronchitis is based on severity only.
You will need inhaled
bronchodilator (formoterol or salmeterol) and inhaled
corticosteroids (budesonide or
fluticasone).
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
