4. Myalgia and Body Aches
Myalgia, or muscle pain, is a pretty vague symptom. Myalgia can be caused by a strenuous workout or injury to a muscle; however, this type of muscle pain will only be in the areas that were overworked or injured. In the case of myalgia from dehydration or by something more sinister such as disease or a side effect of a medication, pain symptoms will be more spread out throughout the body.
Myalgia and body aches are a common symptom of the flu. This pain occurs due to increased inflammation and chemicals from the immune system working hard to fight off the harmful germs. This explains why the aches and pains seem to be all over the body as opposed to just one spot.3Eccles, Ron. “Understanding the symptoms of the common cold and influenza.” The Lancet.
