Hello I have a nearly 5 year old son. he has had issues with his cough since he was a baby on and off, but coughs every morning to clear his throat even if no cough. if he gets a small cold it affects his throat and he will persistently cough especially when laying down in bed like he is trying to clear phlegm from his throat. The doctors have suggested asthma and we were given asthma pumps but as a child who runs around constantly with no breathing issues we knew it was not that and the pumps made no difference. At the moment he had a cough for about 3-4 weeks finally I thought it had almost gone then about 3 days later it comes back again possibly because he has a small cold but seems worse this time he is constantly waking in the night coughing and cannot lay down properly without coughing, he does not appear to have anything else wrong, this morning he was coughing to the point he ran to the toilet to try and be sick 3 times but was not. He has been waking at 5 am and coughs every minute except when asleep! I am going to take him to see an ENT specialist asap but any advice now would be great.
