I got my 2nd covid shot (Pfizer) two days ago and for the last two days have had all those mention as "side effects" of the vaccine. yesterday was a complete write off for me. I nearly passed out just walking to my kitchen to make lunch. feeling better today but am still weak and "dopey" in the brain. and my back still aches. In theory this will all go away fairly quickly, but if I had not gotten covid vaccines and had instead gotten covid I feel this might have been a lot worse.
