You’ve got chills (and they’re multiplying)
“There are certain illnesses that have an abrupt onset, where one minute you’re well, and then suddenly, you’re not,” says Steven Lamm, MD, medical director of the Tisch Center for Men’s Health at NYU Langone Medical Center in New York, NY. That’s very typical of influenza. Flu symptoms include the rapid onset of chills and fatigue, says Dr. Lamm. When you’re coming down with a virus like a cold, you’re more likely to feel mild fatigue or a scratchy throat; symptoms come on more slowly than for flu. Abrupt shaking, chills, and fever are usually signs of influenza or a bacterial infection that needs to be examined soon, suggests Dr. Lamm. Here are some more clear signs a cold is coming—and what to do about it.
You’re sweating like a truck driver in Texas
Sweating often accompanies fever and chills as part of everyday viral and bacterial infections. This type of sweating usually comes on quickly. Sweating can also accompany more serious conditions like cancer, heart disease, glucose control issues or lung disease, but this type of sweating is more chronic. Medications can also cause sweating but this would be abrupt and without the chills and other issues with respiratory infections. These are the signs that excessive sweating is serious.
