Got my booster yesterday. Definitely feeling worse than my other boosters, because up until now I've only had Moderna but yesterday's was Pfizer. Just like every time, the lymph node at my collar bone on that side of my body has swollen up and is achy. Just exhausted to the bone. Plenty of icing and arnica gel, plus the prescription strength NSAID I'm on anyway for my long Covid induced rheumatoid arthritis, but still a lot of arm/neck/shoulder pain. Not looking forward to washing my hair tonight--I've got too much of it to be able to effectively wash it using only one arm/hand. It's still better than when I got my first Covid booster and was silly enough to go ahead and get my flu shot in my other arm--my immune system can't handle that much all at once even though other people are fine with it.
