Body aches and chills
Body aches and chills are also among the first symptoms of flu. If you come down with the flu virus, you can mistakenly blame chills and body aches for something else, such as a recent workout or physical activity. With flu, body aches can develop anywhere in the body, particularly in the legs, back, neck, and head. Chills are also often associated with body aches. Of note, the flu can cause chills even before the development of fever.
Wrapping yourself in a blanket will raise your body’s temperature and can reduce chills. If you have body aches and chills, you can take over-the-counter drugs such as acetaminophen or ibuprofen.
