A fever is a high body temperature. A fever is one way your body fights illness. A temperature of up to 102°F can be helpful, because it helps the body respond to infection. Most healthy teens can tolerate a fever as high as 103°F to 104°F for short periods of time without problems. In most cases, a fever means you have a minor illness.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
How can you care for yourself at home?
Drink plenty of fluids to prevent dehydration. Choose water and other clear liquids. If you have to limit fluids because of a health problem, talk with your doctor before you increase the amount of fluids you drink.
Take an over-the-counter medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin) or naproxen (Aleve), to relieve your symptoms. Read and follow all instructions on the label. No one younger than 20 should take aspirin. It has been linked to Reye syndrome, a serious illness.
Take a sponge bath with lukewarm water if a fever causes discomfort.
Dress lightly.
Eat light foods, such as soup.
