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, clinical professor of medicine and medical director of the Tisch Center for Men’s Health at NYU Langone Medical Center. 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. But if you’re soaking through your clothes and sheets (and you don’t normally have night sweats), let your doctor know. Being drenched in sweat when you aren’t exercising, exerting energy, or doing battle with a known infection is likely cause for concern. It could just be overactive sweat glands or menopause, but serious conditions that cause excessive sweating include cancer, heart disease, glucose control issues, lung disease, or medication side effects. These are the signs excessive sweating is something serious.
