A person who contracts the influenza virus is likely to experience symptoms that last for seven to 10 days, according to Flu.ca. The body constantly fights the virus, resulting in mild to severe soreness. It is also common for people with the flu to experience exhaustion. Age, severity of the flu and location are significant factors that affect the level of pain a person feels when he contracts the flu. Older people often find it harder to flight the sickness. Moreover, the harder the body fights the flu virus, the more severe the pain becomes. Those who live in colder regions also tend to feel secondary aches, as the body typically becomes sore due to cold temperatures.
To relieve sore muscles, Flu.ca recommends drinking plenty of water to hydrate the body and reduce cramps. Dehydration causes the muscles to contract, leading to soreness and cramps. By drinking water, a person lubricates his muscles and gets relief from bodily aches.
