I have a four year old son who has had nasal congestion for just about an entire year. His tonsils are gigantic and he has very foul smelling breath. After this started I began to notice some behavior changes in him as well. He gets upset very easily, throws temper tantrums about everything, and is overall very hard to deal with. He just seems tired all of the time and like he doesn't feel good. He has always been a very happy little boy, but I can just tell that something isn't right since these symptoms started. He has had excema since he was a baby, but this winter he has begun to develop it on his hands and face. Every time I take him to his doctor they say it is viral, but it never seems to go away. I have been looking on the internet and think that there may be some type of allergy contributing to this. He wakes up many mornings with allergy shiners and is constantly rubbing his nose. He sleeps through the night, but coughs while he's asleep. I need some advice on what to do. Are behavior changes like what he's having normal for a child with his symptoms? I mentioned to his doctor bringing him to an ENT, but he doesn't think that's necessary yet. What should I do? I need some advice.
