This sound exactly like yesterday and today so far, so hopefully the worst is behind me. Muscle aches are the worst.Did you only just test positive today? I had a similar experience with my bout exactly a year ago - Monday was fine, little stuffy. Tuesday woke up feeling worse, tested positive. Tuesday evening I took a nap and woke up with a 105 fever. Went back down before I went to sleep. Never hit past 102 after that, so you might be in the clear.
Hopefully you don't get the same sore throat I ended up with. Probably the worst I've had in my memory.
