My husband has these lines of red bumps all over his side. They itch like crazy and look inflamed. We are scared it’s an infection. What is this?

Bed bug bites are often the primary suspects when red, itchy bumps appear on the side of the body. These bites typically occur in straight or zigzag lines, as bed bugs feed in a sequence across exposed skin. The bites themselves are small, red, and swollen, usually measuring around 2 to 5 millimeters in diameter.

Unlike some other insect bites, bed bug bites can cause intense itching and discomfort, often becoming more irritated the more they are scratched. The bites can appear anywhere on the body but are most commonly found on areas that are exposed during sleep, such as the sides, arms, and legs.
