Allergic Itch and Hives

Allergic itch and hives are both conditions that can cause a great deal of discomfort. Allergic itch can be extremely frustrating, and hives can be painful and unsightly. If you suffer from either of these conditions, it is important to understand what they are (and aren't), what causes them, and how to get relief from the symptoms.

By knowing what to look for in terms of symptoms, you can better manage these conditions and get relief from the itchiness as soon as possible.

What is Allergic Itch?

As the name suggests, an allergic itch is an itch caused by an allergic reaction. When your body comes into contact with an allergen, it releases histamines into the bloodstream. Allergens range from pollen and pet dander to certain foods and medications. The histamines cause the blood vessels to swell. This in turn leads to itchiness, redness, and inflammation.

What are hives?

Similarly to allergic itch, hives are an immune system reaction resulting in too much histamine being released into the body. Hives, also known as urticaria, manifests as red itchy bumps or raised itchy rashes. The rash is made up of wheals, which is the medical term for a raised, itchy area of skin that is usually redder around the edges.

What is the Difference Between Allergic Itch and Hives?

Both allergic itch and hives can be extremely itchy and uncomfortable. However, there are a few key differences between the two conditions. Allergic itch is usually localized to the area where you came into contact with the allergen. For example, if you're allergic to pollen, you'll likely only experience itching in your nose and eyes. Hives, on the other hand, can occur anywhere on the body.Unlike allergic itch, hives can occur without any contact with an allergen. This means that the histamines are released for reasons other than an allergic reaction. Hives can be caused by stress, changes in temperature, or illnesses such as the flu. Surprisingly, even exercise can cause hives. Common Causes of Allergic Itch and Hives There are many different things that can cause allergic itch and hives. Common culprits include pet dander, pollen, dust mites, mold, and certain food proteins. Insect stings and bites can also trigger an allergic reaction in some people. In some cases, the allergen is unknown. Dermatologists can help you identify the allergen if you're experiencing allergic itch or hives. They will likely do a skin prick test or patch test. In a skin prick test, the allergen is applied to the skin with a small needle. If you're allergic to the substance, you'll develop a raised, itchy bump within 15 minutes. A patch test is similar, but the allergen is applied to the skin with a patch. The patch is usually worn for two days. If you're allergic, you'll develop a rash at the site of the patch. allergic_itch_on_arms Symptoms of Allergic Itch and Hives The most obvious symptom of allergic itch is, of course, the itchiness itself. This can range from mild to severe, depending on the individual person and the severity of their allergy. Other symptoms may include redness, swelling, bumps or welts on the skin (hives), and burning or stinging sensations. In some cases, people may also experience difficulty breathing, nausea, or vomiting. It is common for hives to come in a variety of sizes and shapes. They can range in size from a millimeter to eight inches. In some cases, someone may have a single hive or a few hives that only cover a small area of the body, while in others, the hives can cover several parts of the body or even the entire body.If you think you may be experiencing an allergic reaction, it's important to see a doctor as soon as possible. They will be able to determine whether or not you are indeed having an allergic reaction and prescribe medication to help relieve your symptoms if necessary.
