What causes rattle in left lung?
Patient: I have a rattle in my left lung when I breath in and sometimes when I breath out and sometimes it comes on the right side but mostly on my left, I ve got phlegm as I ve had a cold and when I cough it up most the time it s white but it has been green I ve been on a corse if antibiotics I m due to finish them Tuesday I ve got a cough that comes and goes as well Doctor: Thanks for your question on HCM.In my opinion you should consult pulmonologist and get done chest x ray to rule out chest infection (pneumonia). As rattles (crepitation) in chest is mostly heard due to retained secretions. And secretions are seen in pneumonia. So we need to rule out this.If chest x ray is normal than get done PFT (pulmonary function test) to rule out Bronchitis. As rattles are also heard in bronchitis.Treatment of both are totally different. Pneumonia needs antibiotics and bronchitis needs inhaled bronchodilators.So better to consult pulmonologist and discuss all these.
