Allergic rhinitis, or hay fever, is a collection of symptoms, predominantly in the nose and eyes, to allergens such as dust, dander and pollen.
Allergic rhinitis affects about 20 percent of the American population and ranks as one of the most common illnesses in the U.S. Two-thirds of all patients have symptoms of allergic rhinitis before the age of 30, but onset can occur at any age.
Patients can be severely restricted in their daily activities, resulting in excessive time away from school or work.
Perennial Allergic Rhinitis: This condition occurs year-round and can result from sensitivity to pet hair, mold on wallpaper, houseplants, carpeting, and upholstery. Non-Allergic Rhinitis: This form of rhinitis does not depend on the presence of IgE and is not due to an allergic reaction. Patients who suffer from recurring bouts of allergic rhinitis should observe their symptoms on a continuous basis.
Seasonal allergens (such as tree, grass and ragweed pollens) are difficult to avoid outdoors, but can be controlled by closing windows and running air conditioners. Excessive exposure to allergens, such as outdoor molds, can be prevented by avoiding lawn mowing and other activities likely to stir these up. Maintaining an allergen-free environment also includes covering pillows and mattresses with plastic covers, substituting synthetic materials (such as foam mattresses or acrylics) for animal products (such as wool or horsehair) and removing dust-collecting household fixtures (like carpets, drapes and bedspreads). Medical treatments include antihistamines which reduce nasal discharge, itchiness and sneezing.
Chronic Fatigue Syndrome (CFS): Some, although not all, studies have reported that a majority of patients with CFS also have allergies to foods, pollen, metals (such as nickel or mercury), or other substances.

We all know the Texas Hill Country is a wonderful place to live and visit, with everything from its beautiful landscape, rich history, vibrant music scene, and friendly people. Cedar Fever stems from inhaling the pollen from the local Mountain Cedar (MC) tree that pollinates in the months of November through March. If you drive down Ranch Road 620 during the height of cedar fever season, you will see a haze that fills the valley.


The sensitized immune system produces antibodies to these allergens, which cause chemicals called histamines to be released into the bloodstream, causing itching, swelling of affected tissues, mucus production, hives, rashes, and other symptoms. The symptoms occur in the nose and eyes and usually occur after exposure to dust, danders, or certain seasonal pollens in people that are allergic to these substances. Allergic rhinitis has no sexual predilection, although boys up to the age of 10 are twice as likely to have symptoms as girls.
One parent with a history of allergic rhinitis has about a 30 percent chance of producing offspring with the disorder; the risk increases to 50 percent if both parents have a history of allergies. Millions of dollars are spent each year on physician services and medication for treatment of this chronic illness. Hypersensitivity to ragweed, not hay, is the primary cause of seasonal allergic rhinitis in 75 percent of all Americans who suffer from this seasonal disorder. Some studies suggest that air pollution such as automobile engine emissions can aggravate allergic rhinitis. The symptoms can be triggered by cigarette smoke and other pollutants as well as strong odors, alcoholic beverages, and cold. If facial pain or a greenish-yellow nasal discharge occurs, a qualified ear, nose, and throat specialist can provide appropriate sinusitis treatment.
Often, the nasal mucosa (lining of the nose) is pale or violaceous because of the engorged veins. Decongestants which can cause shrinkage of the nasal mucosa by constricting the blood vessel inside and thus relief obstruction.
A 2002 study, for example, found that people with depression reported a higher rate of allergic disorders (71%) compared to nondepressed individuals (43%). The researchers think that the inflammatory response may be the link between the two conditions.
One theory is that allergens, like viral infections, may trigger a harmful overreaction of the immune system that can cause fatigue, joint aches, and fever as well as hormone and brain chemical disturbances.
One setback, however, is that every winter a syndrome sweeps over this wonderful land making many ill.
You don’t get a true fever. Even though the inflammation of your allergies may slightly raise your temperature, it is not an infection.


People with sensitivity to tree pollen have symptoms in late March or early April; an allergic reaction to mold spores occurs in October and November as a consequence of falling leaves.
Although bacteria is not the cause of allergic rhinitis, one medical study found a significant number of the bacteria Staphylococcus aureus in the nasal passages of patients with year-round allergic rhinitis, concluding that the allergic condition may lead to higher bacterial levels, thereby creating a condition that worsens the allergies. Other causes may include blockages in the nose, a deviated septum, infections, and over-use of medications such as decongestants. During allergy season, patients with allergies were more likely to experience mood changes, including sadness, lethargy, and mental fatigue, than at other times. However, there is not yet any evidence that treating allergic rhinitis can prevent Parkinson’s disease.

This is known as “Cedar Fever,” and it begins in December and typically runs through February. It grows to a maximum height of approximately 30 feet on the limestone plateaus of Central Texas, the Texas Hill Country, and Austin, and in smaller favorable areas of Texas, New Mexico, Northern Mexico, Arkansas, and Oklahoma. Many people experience an itchy, runny nose, sneezing, nasal blockage, excess tearing and itchy eyes, also known as hay fever (allergic rhinitis). Classic signs of allergic rhinitis may include swelling of the eyelids, injected sclerae (the whites of the eyes may be red), allergic shiners (darkened areas under the lower eyelids thought to result from venous pooling of blood), and extra skin folds in the lower eyelids.
Some evidence suggests that specific immune factors in the allergic response can cause depressive symptoms. Others experience fatigue, mild headache, facial discomfort, sore throat, partial loss of sense of smell, and sensation of ear plugging.
