question: i was treated last week for pneumonia (1/5 of left lung was full), am still on levoquin and feeling better but my now my lungs/lower throat make creaky,squeaky sounds when i'm trying to sleep. if i cough hard, sometimes phlegm comes up and sound quiets..sometimes not. i REALLY need to sleep, these noises and the stomach pain + insomnia from Prednisone prescribed for same issue are keeping me from getting much rest. Is this sound ok, will it stop eventually, and what do you advise for now?
