Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of
bronchitis is more in your case.
Bronchitis can cause coughing with breathing difficulty.
Usually cough is not subsided by routine cough suppressant.
For this you need to
consult pulmonologist and get done clinical examination of respiratory system, chest
x ray and PFT (Pulmonary Function Test).
Chest x ray is needed to rule out other lung diseases. PFT 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 may need inhaled bronchodilators and inhaled corticosteroid.
Don't worry, you will be alright. First diagnose yourself and then start appropriate treatment.. Hope I have solved your query.
Wish you good health. Thanks.
