Pneumonia is usually not contagious, but the fact that you have a recurring fever, and have a moist sound in your lungs, is reason to seek medical attention. You may need an antibiotic.
Your doctor will want to know how high the fever was. He will also want to know if when you cough if you produce mucus. If the mucus was yellowish or greenish, that is an indication of bacterial growth.
A productive cough, fever and chills, chest pain, shortness of breath, loss of appetite, and fatigue are all symptoms of pneumonia.
Even if what you have is not pneumonia, but an upper respiratory infection, it is better to get it checked. Pneumonia can develop from a common cold.
