Nasal Allergies: Related Problems
Allergies can cause nasal passages to swell. This narrows the air passages. Allergies also cause increased mucus production in the nose. These changes result in nasal allergy symptoms. Common symptoms include itching, sneezing, stuffy nose, and runny nose. Nasal allergies can also cause problems in other parts of the respiratory system. Some of the more common problems are discussed below. If you think you have any of these problems, talk with your healthcare provider about treatment choices.
Sinus infections
Fluid may be trapped in the sinuses. Bacteria may grow in trapped fluid. This causes sinus infection (sinusitis) and pain. Sometimes the sinus pain can spread to the jaw and be mistaken for dental problems.
Conjunctivitis
Conjunctivitis is the swelling or inflammation of the conjunctiva. This is the thin layer of tissue that lines the inner surface of the eyelid and covers the white part of the eye. Allergens can irritate your eyes, including the lining of the conjunctiva. This causes eyes to become red, itchy, puffy, and watery. Conjunctivitis caused by allergens is not contagious. But some forms of conjunctivitis caused by viruses and bacteria are highly contagious.
Ear problems
The eustachian tube connects the middle ear to nasal passages. Allergies can block this tube, and make the ears feel plugged. Fluid may also build up, leading to an ear infection (otitis media).
Nasal polyps
Allergies cause nasal passages to swell. Constant swelling can lead to formation of a sac that comes from the sinuses called a polyp. Polyps can grow large enough to block nasal passages. Nasal polyps (unlike other polyps) don't cause cancer. But they can cause mild pain and a decreased sense of smell and taste.
Asthma
Asthma is inflammation and swelling of the air passages in the lungs. The symptoms are wheezing, shortness of breath, coughing, and chest tightness. Allergies, including nasal allergies, are common in people with asthma.
