I started having a slight burning sensation in my left lung when I wake up.  I sleep on my left side due to back problems & quit smoking 6 months ago.  I have an appt with resp Dr. next week but am scared to think what this might be. It seems to have worsen a little.  Any suggestions what it might be?
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of musculoskeletal pain is more likely because of sleeping on that side. But since you were a smoker, we should definitely rule out lung pathology like bronchitis for your burning. So when you consult your pulmonologist, ask him to check for 1. Clinical examination of respiratory system 2. PUT (pulmonary function test). PFT will tell you if you are having bronchitis or not. If PFT is normal then no need to worry about bronchitis. Musculoskeletal pain is more likely in your case. So avoid bad postures in sleep. Take painkiller like ibuprofen. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
