<s>[INST] i have had a dry cough for almost a week. I do not smoke (never have). About 5 days ago, my chest was obviously infected as when I coughed, you could hear the flem, but nothing would come up. Yesterday, my coughing became so bad that I could not stop coughing and started to heave - eyes streaming and pin pricks all over my chest. I have been to the doctor and she gave me antibiotics on Tuesday. The high fever has gone down, but not completely settled back to normal. I am concerned about the pin prick feeling in my chest when I cough as I have never experienced this before. The flem in my chest is till not moving. [/INST] Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you are having lower respiratory tract infection (LETI) mostly. Pneumonia is common cause for LETI. You are having all symptoms like fever, cough, pleuritic pain (pin pricking) suggesting pneumonia. So better to consult pulmonologist and get done1. Clinical examination of respiratory system. 2. Chest x-ray. Chest x-ray is needed to diagnose pneumonia. And treatment of pneumonia is first isolated the causative organism and then start appropriate antibiotic effective against that organism. So get done sputum culture and sensitivity report. Avoid haphazard use of antibiotic because it can delay the recovery and increase chances of Chat Doctor.  So better to consult pulmonologist and discuss all these. And start appropriate treatment. </s>
