Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, you are mostly having
bronchitis.
It is inflammation of airways which causes
cough, mucus expectoration, breathing difficulty etc.
It is not diagnosed by chest
x ray or
CT scan.
PFT (Pulmonary Function Test) is must for the diagnosis of bronchitis.
It will also tell you about severity of the disease and treatment of bronchitis is based on severity only.
You will improve with inhaled bronchodilators and inhaled corticosteroid (ICS).
Oral combination of antihistamine and anti inflammatory drugs is also beneficial.
Don't worry, you will be alright.First diagnose yourself and then start appropriate treatment
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
