<s>[INST] After exposure to spray paint yesterday afternoon,I have been experiencing pains when breathing. It is occurring regularly, but not with every breathe and seems more painful with the exhale, as if someone is squeezing my lungs with their fist. I am an otherwise healthy female. I am concerned that I may have breathed in too much of the paint fumes inadvertently and may be suffering chemical pneumonia. [/INST] HelloWelcome to Chat Doctor, The paint will have lead as its composition, it may be inhaled during exposure to the paint. It may affect lung parenchymal and may cause irritation of the lung tissue, and it may cause patchy consolidation. Because of all this pathogenesis you have developed these symptoms.  I would suggest you to follow1. Oral antibiotics like Tab Autoclave, 625 mg, twice daily for 5 days.2. Spy Pricier AX, which will helps to reduce the symptoms. 3. Oral antihistamines, should be given. Thank you. </s>
