Flushed skin refers to a temporary reddening of the skin, typically caused by increased blood flow to the superficial capillaries, often due to factors such as heat, emotion, or certain medical conditions. In clinical practice, it is important as it can indicate underlying issues such as fever, allergic reactions, or vasodilation associated with conditions like rosacea. A key association is with anaphylaxis, where flushing may accompany other symptoms like urticaria and respiratory distress.
