### input:
I am coughing for a month. I tried all natural remedies from warm water to milk -turmiric and cinimun with honey but nothing helped. I have been to a doctor and they prescribed me Amoxicillian 500mg to be taken 3 times a day for 1 week. I have completed this course and my coughing has declined but not fully gone. When I lay on the bed to sleep I can hear the cough in my chest. Can you please help.

### output:

Hello Thanks for posting at Chat Doctor. Since you have got persistent cough for one month despite being on antibiotics we must rule out if there is any baseline problem with the lungs like underlying asthma or bronchitis or pneumonia. So I recommend you to do a chest x-ray and a PFT. PFT is a breathing test which requires you to blow into a machine and lung capacities are determined. It is a very informative test and will help in the diagnosis of persistent cough and breathing issues. Chest x-ray will show us if there is any pneumonia affecting the lungs. Second since you have no relief despite medications, I recommend you to give a sputum sample (which you cough out) for testing. (aerobic culture, TB gene Expert and sputum for AFB. This will show us what organisms are infecting your lungs and the Chat Doctor.  If all above tests come out normal, and you still have cough, a HRCT chest is recommended which shows us fine cuts of lung tissue to rule out other causes, or hiding infection and also can live information about heart, lymph nodes and other structures in the chest. Please do the above and revert. Wishing you good healthRegards
