Hi, my 2 year old son fell in a pool for about 7 seconds last sunday. On monday he came down with a fever that lasted through wednesday. The highest temperature was 102.4. We gave him ibuprofen, took him to the pediatrician and she said it was a virus, just wait. On thursday his temperature was gone, he seemed like he was slowly going back to normal, but on saturday he started with a cough and runny nose. Tonight he woke up coughing and it sounded like there was phlegm (or liquid) and he had trouble breathing for a minute while he was coughing. Then he fell back asleep. My concern is: could he have water in his lungs even though the doctor didn t catch that 3 days ago? Is there any checkup I should be doing after he fell in the pool? Thank you
