He could be having sinusitis or rhinitis. Does he have associated symptoms of cough, wheeze, breathlessness, post nasal drip etc?
You should try steam inhalation, saline nasal drops and oral antihistamine medications for his complaints and see if it helps with his symptoms.
You should see his doctor and get a clinical examination for a diagnosis and to evaluate if any investigations are required including blood tests, chest xray and CT scan of the sinuses.
Is he allergic to any specific substances or has he had allergic reactions in the past?
Let us now about how he is doing and if you have any other doubts.
Justin does have post nasal drip,(no coughs or weezing) maybe a little breathlessness,he will often clear his throat and spit out yellow mucas like substance.He was treated for a nasal virus but he still has this problem.
His allergy test showed an allergy to ragweed and mold.
I will try the steam inhalation, he is doing a nasal rinse every day.
Thanks for you help
