Yesterday, as night came on, and it got cooler, I decided to go from shorts and t to pants and shirt. I stopped off in the bathroom for a pit stop, and as I was standing there I felt a strange yet somehow familiar sensation. Then I started shivering, and it turned into a full body shiver that I couldn’t stop. I managed to vibrate into the bedroom where I sat on the edge of the bed until it subsided. It wore me out. I put on robe and slippers and warmed up. It was 80 degrees!
Take a COVID test.
Son_of_a_rich, i’ve had a similar sensation before. What were your vitals like yesterday? Did you do something or eat or drink something new?
Nothing unusual prior to the shivers. I think if I feel them coming on again I can stop them before they get out of hand.
Just an FYI …
This was the mother of all piss shivers.
Take your temp
Do you have a blood oxygen tester? Clips on the end of your finger? We used them during covid times to monitor our blood oxygen levels.
bear in mind he said FINGER!!!
I am always amazed (altho’ by now I should no better) at the side-paths Dopers can take from the most innocent statement. 
Both my husband and I have had similar shivers a day before we started showing other symptoms for covid. He’s also had chills before getting the pain that indicates a diverticulitis attack.
Hope it was an one-off thing and you’re fully healthy the next day.
