Hi Jinalshah, 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 called spirometry 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. Best wishes
