User:Mr. Ibrahem/Breakfast, lunch, and dinner sign

Breakfast, lunch, and dinner sign refers to a pattern of itchy small bumps in the skin seen following insect bites. Generally, three to five appear close together at the same time, typically in a cluster or line, on exposed parts of the body such as the face, neck, arms, or legs. The bites may appear pinkish, sometimes surrounded by swelling.

The cause is the bites of insects such as fleas and bed bugs. Unable to fly, fleas and bed bugs generally jump or walk to bite, causing the bite marks to appear in a line or just close together. An enzyme in the saliva of the insect may cause a local allergic reaction, resulting in a larger bump that is itchy. Diagnosis is by its appearance.

Treatment includes antihistamines to reduce itch, and applying a steroid cream to reduce redness and swelling. Prevention lies in insect control within the environment. It is common.
