Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, you should definitely consult pulmonologist
for your symptoms because possibility of post infectious bronchitis is more in your case.
Bronchitis (inflammation of airways) is common after viral upper respiratory tract
infection (URTI) like cold.
Your persistent cough and wheezing are due to bronchitis.
Best treatment for bronchitis is inhaled treatment. Since you are not taking inhaled treatment, you are not improving.
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 is based on severity only.
You will need inhaled bronchodilator
(formoterol or salmeterol) and inhaled corticosteroids
(ICS) (budesonide or fluticasone
Don't worry, you will be alright with all these.
Hope I have solved your query .I will be happy to help you further. Wish you good health. Thanks.
