It’s normal to have a fever every now and again. Your body temperature will fluctuate naturally by about a degree — 36C – 38C every single day. A bit higher before bed. A bit lower in the morning. A bit higher after exercise. And so forth. Typically, it’s no issue and often unperceived.
Sometimes, you’ll get a fever while your body fights off some viral or bacterial infections: the “common cold”, flu, strep throat, chickenpox, pneumonia; dehydration; sunburn; some kinds of medications.
We first wait it out to see if it subsides.
If it doesn’t, then we start to look for causes.
I started having a fever. Low-grade. 38C. Wait it out a few days and see how it goes. Maybe it’s a common cold. Maybe it’s flu-season (not in August). Maybe I’m dehydrated (not more than I’ve been for decades, like most of us are). I live in a desert, but I rarely go outside or into direct sun (yes, telecommuter-life), so it’s not sunburn or heat-exhaustion or (worse) heat-stroke.
Still, we’ll simply wait it out for a few days before seeking medical assistance. It rose and stayed at about 39 to 39.5C.
We went through the same initial Q-A to see if we could find a clue. Any clue…
I hadn’t been traveling or out of the country since before the fall. I haven’t been exposed to anything. I live in A/C. I only go out in the early morning or late evening.
Ah, yes, it’s the annoying — dreaded, even — “fever of unknown origin”.
