Hello! about 4 weeks ago i had a 5 day cold with all the common symptoms. a month now ive had a persistent cough that produces green mucus.i feel completely fine besides that. is this normal?could i have had pneumonia and the cough is just lingering?

Sometimes after an upper respiratory infection, you begin to have bronchospasm from the cough and then the cough continues. You also likely have airway inflammation which will also lead to cough. A bronchodilator inhaler along with a steroid inhaler will likely get the cough to go away. So, see your doctor to get treated. Good luck!

Any cough lasting longer than 2 weeks needs to be evaluated by a pulmonary physician. If it is not getting better, do see a doctor.

It is not unusal to start with a head cold that would be considered an upper respiratory infection and then proceed to an infection in the lower respiratory infection such as bronchitis or pneumonia. Often it also starts as a viral infection as the head cold and can proceed to a bacterial infection lower down but not always. The cough is due to the inflammation. Best to be seen by your physician.
