Skin reactions are often easy to ignore because they’re visible, familiar, and usually harmless. A bit of redness or itching typically fades on its own, so people don’t always take it seriously.
Most rashes are minor, but patterns matter. When skin symptoms combine with other changes, they can signal something more serious.
One common reaction is Urticaria, which causes raised, itchy welts that can appear and disappear quickly or spread across the body.
However, their significance changes when they occur with symptoms affecting breathing or circulation.
