Hi, My father is having parkinsons. He is not able to move. In the last couple of months he had fever twice, but he also have mucus developed which he cannot bring out since he is unable to move. Doctor advised chest xray and attached are the results. Please can you advise what could be the issue and probable treatment. He coughs a little while eating food, not all the time. But we can feel he has mucus inside his throat. Please advise.
