Had several reactions #2 shot of Pfizer. Heart rate was high as if I was jogging for about 2 hours after the shot. My arms, face, and chest were flushed like I was hard liquor drunk, and I was hot like the same. After all that passed I had a rash spread from injection site down my arm, across my chest and neck and down my other arm. Was crazy tired and all my joints were sore for 2 days. The injection site stayed very sore for a week and a half. Strange stuff.
