Hi, my son is 3 years old, he has been coughing for 5 months especially during the night and soon he wakes up. I took to many doctors, his chest is clear but he has a blocked nose and i have a feeling that his nose condition is causing the cough. he eats well, plays well and he looks ok but this cough is not going away, and gets worse when there is a change in weather. what to do?
Welcome to the ChatDoctorI understand your concerns but don't worry. The reason for your children cough can be allergic reaction or post nasal Chat Doctor.  I would recommend you to start him on montelukast for a few months (usually advised for 3 months). This will improve his allergic tendency. You may use elastin or steroid sprays for good benefits in nasal congestion and post nasal
