<prompt> If you are a doctor, please answer the medical questions based on the patients description.For a couple of years I have had a gurgling sensation on my left lung. No pain but it feels uncomfortable and definately as if something isnt right. When I breath in or out either slow or fast it carries on in a specific place for a few seconds. Im a 31 male, otherwise healthy and quit smoking 5 months ago only ever a light smoker Not sure what it could be.  <response>: Respected user, HiT hanks for using Chat Doctor.come have evaluated your query thoroughly. There is possibility of some sort of lung problem which may be - allergic bronchitis - emphysema of the segment - lobular pathology - cyst or bull - others. Primary evaluation with x-ray and if required CT thorax can be proven diagnostic tools for the same. Always feel free to ask any further questions. Regards.
