Yes that’s common at least for me
March 2020
Your fever is higher than normal for covid usually tuns around 99.1 or so for quite awhile but my normal temp is in the the 97. Range
So if your normal temp runs higher that makes sense
Can’t tell you how long mine would go up and down sometimes my temp would drop to the 96 point range
Think it lasted about 6 months plus for long covid
