Thanks for your question on Healthcare Magic.
I can understand your concern.
No, steroid injection is not a good thing.
In my opinion, you are mostly having post infectious bronchitis.
Bronchitis (inflammation of airways) is common after viral upper
respiratory tract infection (URTI) like cold.
So better to
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 mostly improve with inhaled bronchodilators (formoterol or
salmeterol) and inhaled corticosteroid (ICS) (
budesonide or
fluticasone).
ICS are safer than injectable steroid.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
