Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of post infectious bronchitis is common in your wife's case.
Bronchitis (inflammation of airways) is common after viral upper
respiratory tract infection.
She was having viral infection 4 weeks back and now her wheezing, chest congestion etc are more suggestive of bronchitis.
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.
And treatment is based on severity only.
She will need inhaled
bronchodilator (formoterol or salmeterol) and inhaled
corticosteroids (ICS) (budesonide or
fluticasone).
Don't worry, she will be alright.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your wife. Thanks.
