- Children with perennial allergic rhinitis may also have the following:

- Breathing through the mouth
- Poor performance in school
- "Allergic salute." This is when a child rubs his or her hand upward across the bridge of the nose while sniffing. This may cause a line or crease to form across the bridge of the nose.
The symptoms of allergic rhinitis may resemble other conditions or medical problems. Always consult your child's health care provider for a diagnosis.

The link between allergic rhinitis and asthma
Controlling asthma may mean controlling allergic rhinitis in some patients, according to allergy and asthma experts. Allergic rhinitis is a common problem that may be associated with asthma.
Guidelines from the World Health Organization recognize the link between allergic rhinitis and asthma. Although the link is not fully understood, one theory asserts that rhinitis makes it difficult to breathe through the nose, which hampers the normal function of the nose. Breathing through the mouth does not warm the air, or filter or humidify it before it enters the lungs, which can make asthma worse.
