Thanks for visiting HCM.
I wish you must have told about your age, smoking
habbits if any.
Acute cough i.e cough lasting lesser than 3 weeks are usually viral in origin or due to super added bacterial infection. Pulmonary Tuberculosis
should also be ruled out if there is cough for 2 weeks.
I think you must go for sputum for acid fast bacilli, gram staining, culture and sensitivity, routine microscopy. If these are normal then should go for a simple breath test
to look for asthma or obstructive lung disease
The treatment depends on the diagnosis made, so visit pulmonologist in your area with the abovesaid investigation reports.
