I had pneumonia
about 2 months ago, diagosed with a chest x-ray. Antibiotics
cleared it up in about a week. Then a couple weeks later I developed severe sore throat, productive cough, pressure in ear, and runny nose which all lasted few weeks. Recently I started to feel normal, but still have lots of greenish-yellow mucous and always have to hack and spit. And when I take a deep breath out, my lungs make a grunting or vibrating noise. Possible sinus infection, pnuemonia, or worse?
