Isn't pneumonia very obvious? my mom says i would be in bed *almost dying* if i had it, but i'm fine. just cough and green mucus. i am very worried

Pneumonia: Pneumonia is a condition diagnosed by a constellation of symptoms (cough, fever, shortness of breath) with evidence on chest X ray of lung involvement. It can be cause by a bacterium, virus, fungus. Severity of symptoms range widely. Chest X ray evidence is really diagnostic. Everyone reacts differently to infections, but most people feel pretty awful if they have pneumonia vs bronchitis.
