Rationale 1: Rapid release of histamine on a large scale throughout the body is responsible for anaphylaxis, a life-threatening allergic response that can result in shock and death. A number of chemicals, insect stings, and foods, and some therapeutic drugs, can cause this widespread release of histamine from mast cells.
Rationale 2: Swelling is a localized reaction and occurs with the inflammatory response of histamine.
Rationale 3: Pain is a localized reaction to the histamine release.
Rationale 4: Redness is a localized reaction to the histamine release.
