[|AI|]  Hello, Welcome to Chat Doctor, As your son is having allergic reaction it is very important to identify the allergen causing these symptoms. Your son require Skin prick test(SPT) to detect the allergen like dust, mite, food and chemical causing these symptoms to your son. By doing the SPT we can detect the allergen, and you can avoid allergen causing these symptoms. If you cannot avoid the allergen like food you can go for immunotherapy. There are two type of immunotherapy they are sublingual immunotherapy and subcutaneous immunotherapy. Treatment by this will improve your son condition. Thank you.
