I rolled out of bed about an hour ago and I already feel like I need a nap, probably thanks to the COVID-19 booster I got yesterday afternoon. I haven’t felt a reaction to the previous shots I got, but whether or not you feel it seems to be pretty random. I was already feeling it last night as I was getting ready for bed, wondering, “Why is my arm so tight and sore?” This morning all my joints are achy, my arms are still tight and all my muscles feel like I just finished a workout at the gym.
