Ever feel just "off"

I am off today. Do any of you have days where you are just “off”? I do not have any symptoms that a physician would be able to diagnose or treat. Parts of me are warm and parts of me are cold (my hands and deep down in my bones).

My hands and fingers do not look swollen but they feel too thick to hold anything - and I can only type using one finger on a touchscreen. My head feels fuzzy inside - almost as though I have a hangover, when I haven’t had an alcoholic beverage in 30 years. Out of phase off.

I know exactly what you are talking about, I was like that for two weeks. I had everything you talked about and I would get a slight fever towards the end of the afternoon and the evenings I got nauseous quite a bit. I feel better this week although my Dr did some blood work and she can’t find anything. Who knows, my body never does what makes sense.
