<s>[INST] Why is it that every time I go to sleep on my back and my sides I get this sharp pain when I breathe in/nearby my right lung? It is starting to worry me since it has been going on for a week now. All I know is that I do burn wood and the smoke is thick when I inhale. My husband and I burn wood all day long, is this  something I should be worried about? [/INST] This pain is pleuritic pain due to inflamation of pleura.start using proper mask while working.start antibiotic and NSAIDs tablet. </s>
