The specific cause of body aches (myalgia) are the interleukins, which are primarily produced by the macrophages. These interleukins cause pain, body aches, hypersensitivity of the nerves, etc. Some of the interleukins (such as IL-2) cause the fever seen during the flu, and probably the headaches. Since these interleukins are produced in response many different kinds of bacterial and viral infections, symptoms such as fever, myalgia, and headaches can be seen in infections by many different etiologic agents.
Some health conditions can cause pain throughout the entire body. Muscle pain may be a sign of a condition affecting the whole body, although all over pain can also be caused by inadequate blood flow to the tissues and nervous system disorders. Total body pain can be debilitating, and it can significantly affect a person's quality of life. Chronic hypoxia can cause pain all over the body. Chronic hypoxia is a state in which oxygen transport throughout the body fails to meet the tissues' demand for oxygen.
