Allergy Symptom 
For some people, nasal allergy symptoms are mild. For others, they're severe. Anyone who has nasal allergies knows these common symptoms well: 
  • Sneezing. The nasal mucosa membrane protects the inside of your nose against invasion by foreign substances. When something irritates this membrane, you sneeze. The sneeze is an attempt to expel whatever is causing the irritation. 
  • Runny or stuffy nose. During an allergic response, chemicals are released that cause the vessels and glands in the area of your nose to become leaky. This releases mucus. These same chemicals cause the nose's blood vessels to enlarge. This leads to congestion. 
  • Inflamed nostrils 
  • Itching eyes, nose, and throat. Histamines and other inflammatory chemicals released during an allergic response act on the mucous surfaces of these areas, causing them to itch. 
  • Allergic shiners. Dark circles under the eyes are a result of increased nasal congestion. 
  • The "allergic salute." This is the upward motion children with nasal allergies often make. They rub their nose with the palm of their hand to ease their persistent itching nose. Some children "salute" so often it creates a crease mark across the bridge of their nose. 
  • Watery eyes and swollen, red-rimmed eyelids. Called allergic conjunctivitis, this condition develops in as many as 3 or 4 out of every 10 people with seasonal allergies. They develop swelling, watering, and itching when allergens touch the membranes in and around their eyes.

Bronchodilators
Allergies can play a major role in many of asthma. If you're prone to asthma or bronchospasms, your kit should include an inhaler. Short-acting inhaler -- bronchodilators -- are available only by prescription. For a mild attack, a couple on the inhaler will quickly relax the that have tightened around the airways. Inhaled , although they don't immediately relieve symptoms, may also be for long-term control of asthma. These medications control inflammation in the airways.
