Re: I here sounds in my left lung
I would ask Dr for a chest xray. This has been going on a long time and must be pretty loud for your daughter to hear it. The dry cough is most likely related and an xray should provide some clues. If it is normal, a CT scan might be helpful to rule out pulmonary fibrosis, scarring of the lung, that can occur for a variety of reasons. Pulmonary function tests may be helpful as well if no answers are readily obtained.
