hi doc, this is carly and I want to ask something about my child, my child has hazy densities seen on her right lower lung according to her x-ray. Since she was born we heard something from her chest and it s kind a noisy,so we decided to consult her, actually she was already 5 months old right now,. the impression of her x-ray is pneumonia, is this something to worry about? what causes hazy densities?
