So here’s your bottom line: a typical flu without meds runs its course in 7 to 10 days, but the cough and tiredness can stretch to 14 or 21 days. That’s three weeks of feeling “off” if you’re unlucky. But the worst pain—the part that makes you whimper—usually ends after day four.
If you’re still feeling terrible after ten days, or if your fever comes back, call a doctor. That’s not being weak; that’s being smart. The flu can turn into pneumonia or other nastiness, and no amount of chicken soup will fix that. So respect the virus, but don’t fear it. You’re tougher than a cough.
Now go get some tissues, a blanket, and a show you’ve seen twenty times. Your body knows what it’s doing. Just give it time. And maybe one more nap.
