If you have a cold or the flu, symptoms can last from days to more than a week. But if your fever, cough and feelings of being run-down persist, you may have pneumonia. This lung infection inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing.
