Anybody have trouble regulating body temperature after COVID?

I also get feelings of faint.

Yes! I experience this too. Lately it has gotten worse to where my face will turn red and I will start sweating profusely. I can be laying in bed ac on 74 with 2 fans blowing on me and sweat will just pour out of me then it stops I put on dry clothes and then I'm cold. It's extremely frustrating and uncomfortable and adds to my fatigue.

Yes.
And if I have coffee or hot food, I stay hot for awhile.
I tried writing down the time of day it occurs and it seems to happen more often early evening.
I might be wearing my summer pj’s all winter!

I feel chilled most of the day, but by early afternoon I am freezing. When others are hot, I am cold. That said, I’d rather be chilly than too hot. I feel for those who can’t cool off.

Male...My thyroid test came back normal and all my bloodwork.

I experienced 3 bouts of Covid. The first, just before there was much news about it. Once the news spread, I was able to recognize my experience for what it was and had more patience with myself for the long recovery time.
Prior to this my normal temperature was 98.6- always consistent , unless I was sick. I could tell the precursor to a fever if my temp dropped by .2 degrees with back ache. Shortly after, it would rise to whatever temp was required to rid me of the illness. My sensitivity to external temperature was such that I could, by discomfort, know when it rose over 69 degrees and at 72 had to take evasive action. I was raised I enjoy the cold because I run so warm. In N Carolina, I was in t-short and jeans to walk my dog, when other women my age were in mufflers, gloves and down jackets in the winter in SF where temps do not get high regularly. And I have lived in Fairbanks where I was happy as a clam.
After Covid, and it became worse with each bout, my normal temperature seems to have "stabilized" at 97.4. The weird thing is that with no explanation, I will find myself very cold , cold feet, hands though I usually, even now, tend to run hot-to me. At those times I will take my temperature and it will have dropped to 95 or as low 94.5 and I have to take action to warm up. I will not be "sick" just cold and a warm bath will take care of it.
Hearing everyone else's experiences have been a bit of a reassurance as I am well past menopause (68) and my husband has just thought I have gotten strange.

Since my last bout of covid in which I developed covid myocarditis I am having horrible hot flashes. I'm past menopause. I don't have an adrenal tumor which can cause hot flashes. The MD'S r stumped. Now there blaming it as long covid symptoms. I wonder if it will ever end.
My normal temp is 97. When I have 99.5 it's fever for me although the medical community says it's not. There r new studies, however, that r confirming as u age ur normal temp in the 65 & older crowd is much lower.
There is a post covid illness of Reynauds syndrome, cold hands & ft.
Good luck & feel good!

Yes me too. I am 75 so not menopause....sweatshirt on, then off....had no idea it could be related to long covid. Had covid last Christmas. 2023

I have the cold hands and feet. Wear socks at night....sometimes gloves.

Get checked for Reynauds syndrome. If not, it appears ur body is having a hard time regulating ur temp, too. Exercise is good too, as it moves the blood around to all extremeties.
Do u live in cold weather, keep ur home very warm.
I also suffer from Reynauds but have had it b4 the covid outbreak. I live in South Fl but when there is a cold snap I also wear sweat socks on my ft & hands to keep warm inside my house. It hurts.
It is somex hereditary. My dad & daughter have it, too.
I don't think they know all of the ramifications of long covid yet. They say the vaccinations minimize ur chances of long covid. Being a nurse & understanding the medical literature i agree w/ them.
Good luck!
