My son recovered from a long cough for almost 1.5 months which used to come when he sleeps(noon/night). 2 week after that he got fever and we have paracetamol(3.5ml twice 6 hrs gap) and next day he recovered. After that he got dry cough and runny nose. Now he is coughing during the day and also when goes for sleep(noon/night) it gets worse. During the day he eats, plays well also once the cough stops he sleeps well. I could also observe little bit snoring during sleep and whenever he changes the position it stops and after a minute it resumes again. His saturation level is 96, pulse is normal. Breathing is normal during the day and when sleeps sometimes it's little louder. Doctor says it's viral due to drastic change in weather and due to change in location(travel hometown)he repeatedly got infected but I am worried because of the long running cough if it turns to any other permanent issues. Based on the above information can anyone tell me what could be the issue and any suggestions?
