Why Does Hives Appear on the Skin? Surprising Triggers You May Not Know
Hives (also called urticaria) are itchy, raised, red or skin-colored welts that can appear suddenly anywhere on the body. From the image, the bumps look consistent with hives or an allergic-type skin reaction, but many conditions can look similar—so this is general guidance, not a medical diagnosis.
Why Do Hives Appear on the Skin?
Hives happen when the body releases histamine and other chemicals into the skin. This causes blood vessels to leak fluid, leading to swelling, redness, and itching.
