What are the Symptoms of PAP?
Primary PAP usually starts without notice and then gradually gets worse until a feeling of breathlessness (dyspnea) becomes apparent and progresses. Some patients also have cough and / or may produce small amounts of whitish phlegm (sputum). Fever can be present if infection is also present. Rarely, an affected individual may cough up blood (hemoptysis) or have chest pain, especially if lung infection is also present.
