Just wanted to say that if you do take him to a doctor they might suggest operating on it which would be very bad. Many children are now getting their adnoids taken out(it used to be tonsils, but then that was shown to be harmful, ofcourse)with awful results. You don't ever want a doctor to take anything out, especially when the problem can easily be remedied using natural healing. That being said I think that the best thing for him would be to make sure he gets lots of rest and feed him only organic raw fruits and vegetables for the time being. Absolutly no dairy(especially no dairy, this gives mucous and clogs the lymph system), grains, meat or anything you didn't make yourself. Give him lots of good clean water.
