<s>[INST] I have had a cough for about 5 mnths now. I seen a doctor last Friday. She said I have underlying asthma issues. I am still coughing alot. For the past hour I have kinda had pain in my chest. Could something be strained from coughing or is it possibly something else? [/INST] Hi thanks for asking. Here long duration cough is there. If associated history of fever and weight loss then sputum for TB done. You do your pulmonary function test to rule out asthma and about restrictive or obstructive lung lesion. Avoid smoke strictly.Don't take spicy food. Here cough can be because of chronic bronchitis. So better to do sputum for TB and PFT first. Then according to report further work up done. If Chat Doctor. Don't worry. You will be alright. Thank you </s>
