Muscle Aches

When you have an infection like food poisoning, your muscles might hurt. Because your immune system has been activated, inflammation has resulted.

During this process, your body produces histamine, a substance that helps widen blood vessels so that more white blood cells can fight the infection.Histamine helps in the restoration of blood flow to infected areas of the body. Histamine, like other immune-related substances like cytokines, can move to other regions of your body and trigger pain receptors. This can make particular sections of your body more sensitive to pain, leading to the dull pains that come with sickness.
