Hay fever symptoms include sneezing, watery eyes, and congestion. Hay fever can cause a rash. Learn about the causes and symptoms of hay fever rash.

Hay Fever

Hay fever symptoms are fairly well-known. Sneezing, watery eyes, and congestion are all allergic reactions to airborne particles such as pollen. Skin irritation or rash is another symptom of hay fever that gets little attention.

Hay Fever

Almost 8 percent of American adults get hay fever, according to the American Academy of Allergy, Asthma, & Immunology. Hay fever, also known as allergic rhinitis, is not a virus. It is, instead, a term used to refer to the cold-like symptoms that appear as a result of airborne allergies. While some people experience these symptoms on a year-round basis, for many people symptoms are seasonal, depending on their particular allergies.

Here are a few ways to determine if your rash is related to hay fever, or from a different cause.

Can Hay Fever Cause a Rash?

While other symptoms of hay fever are traced to breathing pollens and other allergens, hay fever rashes can often be traced to allergens coming in direct contact with the skin.

For instance, you may be touching various pollens in plants and flowers if you are working in the yard. When compounded by the fact that you are stirring up these pollens by working in flowerbeds, you have a recipe for a skin eruption.

A rash may be mistaken for hives, which are generally caused by an allergic reaction to something that has been ingested or breathed. However, hives can occur as a result of hay fever. The first symptoms you’ll notice are itchiness and red patches or eruptions on the skin. These look more like welts than bumps, with edges that are clearly defined. The surface of the skin will appear swollen, almost as if you’ve been scalded.

As time goes on, the spots may increase in size, and even disappear and later reappear. Hives tend to turn white when pressed.

Atopic Dermatitis

Atopic dermatitis is not caused by hay fever, but can be made worse by hay fever. Atopic dermatitis is more common in infants and young children. It can appear as an ongoing rash, and it usually includes a host of other symptoms.

Atopic dermatitis appears as patches of dry, bumpy skin, especially on the face, scalp, hands, and feet. Other symptoms may include oozy blisters, ear discharge or cracking, and lizard-like skin changes that appear as a result of constant scratching. The itchiness is usually described as intense or unbearable.

Other Causes of Rash

If you’ve been spending quite a bit of time outdoors recently, you may assume your skin rash is related to hay fever, but there are other factors that could be to blame. Heat rashes are common, so if you’ve been spending time outside, heat could be the culprit. You also may have unintentionally come into contact with poison oak, poison ivy, or some other poisonous plant.

Numerous other factors can cause skin rashes. You may have an allergy to the laundry detergent or soap you’re using, or you may have a cosmetic injury.

Lastly, it shouldn’t be forgotten that hay fever can cause generalized itchiness. In fact, it’s one of the main symptoms. All that scratching can cause skin irritation, leading patients to believe they’re suffering a rash when really it is simply a reaction to scratching. Antihistamines (such as Benadryl) can help reduce that itchy feeling, cutting down on skin irritation.

Narrowing Down the Cause

One key to finding the cause of your rash is to observe how long the rash persists. A rash that keeps coming back may be related to hay fever, rather than temporary exposure to something. Also, what time of year does the rash normally appear? If you notice you’re developing recurring rashes consistently during certain seasons (like spring time), it may be related to the pollens of that season.

You should note that allergic reactions aren’t limited to the pollens in the spring. Fall allergies are common and, in some areas, trees and certain plants grow in the winter and summer that can cause skin irritation. Ragweed and grass can cause hay fever during spring and summer, the two best-known seasons for allergy problems.

Other Non-Histamine Symptoms

In addition to a rash, patients may also experience below-the-eye puffiness as a reaction to hay fever. Dark circles may also begin to appear. These are known as allergic shiners. Also, a person with hay fever may feel fatigued without realizing hay fever is the culprit. Headaches can also occur. Some people with hay fever may feel irritable and experience memory problems and slowed thinking.
