According to the on-line version of the Merck Manual of Diagnosis and Therapy:
"Symptoms start 24 to 48 hours after infection and can begin suddenly. Chills or a chilly sensation are often the first indication of influenza. Fever is common during the first few days, and the temperature may rise to 102 to 103 °F (approximately 38 to 39 °C). Many people feel sufficiently ill to remain in bed for days; they have aches and pains throughout the body, most pronounced in the back and legs."[1]

Common symptoms of the flu such as fever, headaches, and fatigue come from the huge amounts of proinflammatory cytokines and chemokines (such as interferon or tumor necrosis factor) produced from influenza-infected cells.[2][45] In contrast to the rhinovirus that causes the common cold, influenza does cause tissue damage, so symptoms are not entirely due to the inflammatory response.[46] Symptoms of influenza may include:
Body aches, especially joints and throat
Coughing and sneezing
Extreme coldness and fever
Fatigue
Headache
Irritated watering eyes
Nasal congestion
Nausea and vomiting
Reddened eyes, skin (especially face), mouth, throat and nose
