Yep, I'm also loaded up on those and had a 'flu shot this year.

Concentration's also shot and I'm getting little pain explosions all over, have a headache and the arthritis in my hands and fingers is off the charts.  No fever, though, but it's as though my body can't properly regulate its own temperature.

Really weird; can't recall having had symptoms like these before. 

Most concerning would be breathing and super high temperature.  Probably just a cold.  How exposed are you?  I don't think I have left my house since some time in December, to grab milk from a local store.

Breathing is OK and temperature hasn't gone over 99.3°F.  Grew up with a litany of respiratory ailments, so am fairly aware whenever anything pulmonary starts to feel odd; no tightness, wheezing, lack of lung capacity, etc., though.

Unfortunately, I am in a high-contact / high-risk category since work-from-home isn't currently an option for me.  That said, I am masked and washing hands routinely as well as social distancing inasmuch as is possible.
