Many people — especially children — get used to hay fever symptoms. But getting the right treatment can reduce irritating symptoms. In some cases, treatment may help prevent more serious allergic conditions, such as asthma or eczema.

Your doctor will do a physical exam and may also recommend a skin test to find out what you are allergic to. In a scratch test, for example, small amounts of suspected allergens are applied to the skin with a needle prick or scratch. If there is an allergy, the area will become swollen and red. Sometimes a blood test may be used to find out which allergens you react to.
With young children, it can help to watch what they do. For example, a child with allergic rhinitis may wiggle his nose and push it upward with the palm of the hand.
