Allergic

Experiencing an allergic reaction, a hypersensitive immune response to a normally harmless substance (allergen) such as pollen, food, or animal dander. This reaction manifests with various symptoms, ranging from mild discomfort like a rash or sneezing to severe, potentially life-threatening reactions like anaphylaxis. The body's immune system incorrectly identifies the allergen as a threat and produces antibodies, leading to the release of histamine and other chemicals that trigger the allergic response. Sensitivity can vary widely among individuals.
