question: Hello doctor, My 8-year-old daughter went out of town. She went for a month. Last night her and my 10-year-old son were saying their lungs hurt to breathe deep. Today both have pain in the chest when sneezing or coughing and deeply breathing. I believe they inhaled into their lungs salt water mixed with strong chlorine. Please advise. Tonight my son says he is fine now but my daughter is still having the problems.
