4. Fever
A fever is an obvious sign that something is wrong. A fever can come on suddenly or overtime. Many people can tell when they have a fever. A fever itself can cause your skin to feel hot. It can also cause chills and sweats. It may be hard to get warm or even get out of bed.
A fever is a symptom of the flu, but it can also be the cause of other symptoms associated with the virus. Fevers can come and go or may last throughout the entire time the virus is in your system. Medications and warm baths can help lower the body’s temperature and treat the symptoms.
Fevers can lead to dehydration, so it’s important to drink plenty of fluids if you are battling one. It’s also a good idea to get plenty of rest and try to eat even if you do not have an appetite.
