Allergic patients have a characteristic look that a health care provider can pick up on.  Many of them will be quite obvious to the non-medical person's eye.  They include:

·         Clear, watery discharge from the eyes

·         Red eyes

·         Dark circles under the eyes

·         Thin discharge from the nose, but thick discharge does not rule out allergies.

·         A horizontal crease along bridge of the nose.  This suggests that the patient has been rubbing his nose because of itching.

·         Lines called Dennie-Morgan lines are noted below the lower eyelid. 

·         When a doctor looks at the patient's nose, the lining will be pale or have a bluish hue and there may be some swelling inside.     

• The doctor may notice fluid behind the ear drums and a red throat with post-nasal discharge and enlarged tonsils.
