Thanks for your question on Healthcare Magic.
I can understand your concern.
You are having
chronic cough (cough for more than 2 weeks).
Common causes for this are bronchitis,
lung infection,
tuberculosis, asthma and
lung cancer.
All these are curable. But you should first diagnose the problem and then start appropriate treatment.
So better to
consult pulmonologist and get done clinical examination of respiratory system, chest x ray and PFT (Pulmonary Function Test).
Chest x ray is needed for lung infection.
PFT is must for the diagnosis of bronchitis and asthma.
You will need antibiotic, antihistamine, inhaled bronchodilators (formoterol or salmeterol) and inhaled corticosteroid (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.
