[|Human|] my 8 year old son sneezes / sniffles every morning and at night.  this has been happening for years.  what could be the cause? I have changed his sheets, given him a mattress and pillow cover. we have no pets, no smokers, no forced air heat/cold... thx
[|AI|]  Hi, thanks for the query. Your is suffering from Vasomotor Rhinitis. Change in temperature, humidity, blasts of air or dust can cause sneezes. Avoidance of sudden changes in temperature, humidity, blast of air & dust. Start Steroid nasal spray with antihistamine. Certainly above treatment will give you much relief but if relief is not up to satisfaction level then consultation with your ENT doctor will become essential. Hope this information helps you, take care and have a nice day.
