<s>[INST] I have had a chest cold for a week.  I have lots of phlem in my chest so I cough a lot trying to get it out.  When I cough really hard (so hard that I sometimes throw up) my breasts get a tingling/painful sensation as I cough and for a few seconds after.  It hurts.  Do you know what this is? [/INST] Thanks for your question on Chat Doctor. I can understand your situation and problem. Chest pain on coughing is characteristic feature of pleurisy. Pleurisy is inflammation of pleura. And it is seen commonly with lower respiratory tract infection (LETI) - pneumonia. In your case possibility of pneumonia is high. Because you recently had cold and pneumonia is common after cold. You are also having a lot of chest congestion, so possibility of pneumonia is high in your case. So get done chest x-ray for the diagnosis of pneumonia. You may need antibiotics, bucolic and expectorant Chat Doctor.  Hope I have solved your query. Wish you good health. Thanks. </s>
