I am now wondering if I should have avoided taking the Covid-19 vaccine (I took two doses of Moderna's mRNA style vaccine). That is because I have noticed a number of damaged looking blood vessels in my legs. This is damage that I never saw prior to taking the vaccine (at least if I ever did see similar damage in the past it eventually went away) and thus I now wonder if the vaccine was a contributing factor (though not the only factor, since I know some other things I did made it difficult for my legs). I prefer not to mention the things I did which made matters difficult for my legs, other than to say I have a job which requires me to stand the entire time I am working and some shoes I have been wearing for the prior two months have damaged heels.
When I took the first dose the needle prick was more painful than I expected. Within a couple of hours I developed soreness in my arm and it lasted for 24 hours. I never had soreness as intense as that from flu vaccines nor from other injections.
When I took the second dose the pain from needle prick was very mild (like what I expected the prick from the first dose would be like). I told the Dr./pharmacist (who injected me at a pharmacy inside Costco) that this injection was far less painful than the first. He said the needles used this time are different than some used before for the vaccine. I asked since that is the case, is this vaccine produced by a different manufacturer than the first one. He gave me a look of disapproval. Maybe he though I meant that maybe the vaccine was not really Moderna's this time. But what I meant was maybe Moderna had a third-party company fill the vaccine vials (or needles?) for them (or manufacture the vaccine on behalf of Moderna) and maybe that company was different than whichever company filled (or manufactured) the ones for my first dose. The pain in my arm that I experienced from the second dose was more painful than which I experienced from the first dose and the pain lasted 36 hours. I had both injections take place in the same arm.
