At my recent visit to my oncologist, I thought I heard him say under his breath something about being immune compromised and not having a fever when you’re sick. So I asked ChatGPT (I know) and it seems that that’s a real thing. I don’t have enough immunity to trigger a fever in my body. So it’s more important for me to pay attention to how I’m feeling and if things are changing as opposed to worrying about whether I have a temperature or not. I find this kind of interesting because when I left the hospital, they said, “If your temperature is 100.4 or higher, go to the ER immediately!” However, it seems I may never reach that point. Has anybody else been told (or experienced) that you could have an infection or be sick without a fever? I guess I should clarify: I realize that healthy people can have an infection (cold, UTI, etc) without a fever. Maybe I should say “a serious infection that would normally spike a fever in a healthy person”.
