Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you are mostly having post infectious bronchitis. It is common after
lung infection.
It is actually due to inflammatory process in trachea after infection.
So better to
consult pulmonologist and get done clinical examination of respiratory system and PFT (pulmonary function test).
PFT will not only confirm the diagnosis but it will also tell you about severity of the disease and treatment of bronchitis is based on severity only.
You will need newer longer acting inhaled
bronchodilator like formoterol or
salmeterol. Also start inhaled
corticosteroids (ICS) (budesonide or salmeterol).
No need to worry for ICS. They act locally without any systemic side effects. They are best in action to reduce inflammation in trachea.
Don't worry, you will be alright.
Consult pulmonologist and start newer inhaled treatment.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
