Had it last year. 103° temp, had to go to ER to get fluids, outside of that, I didn't leave my bed for 6 days. I came down with it on a Saturday and didn't have the strength to even go downstairs until Friday. Lost my sense of smell, but it did come back, although it has changed. While I had acute Covid, I noticed that I did not experience the tinnitus I usually have. That came back too. Am very easily fatigued still.
