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.
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.
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.
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.
