The Symptom: Chills and Fever

What It Means: Chills are the way the body generates heat when it feels cold. They usually precede a fever, the body’s method for defending itself by raising its temperature to fight a virus.
When to Worry: Call your doctor if your temperature rises above 102 degrees, if a fever persists for 72 hours without breaking, or if you also have shortness of breath or dizziness.
Home Remedies: To stay hydrated, sip your favorite liquids. Sponging off with warm water may also give you relief.
Over-the-Counter Remedies: Acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve) can lower a fever that’s making you uncomfortable.
