Update: Had my second shot on Wednesday. As with the first, I have "COVID arm" but to be honest, I think the first time was worse, which, according to the second place I went, MAY have been the needle size. Three weeks later and I am STILL sore from the first time. I have read (and confirmed through nurses) that it can be normal swelling from the muscle "injury" OR an immune response. For those of us with MS, we are familiar with the frequent inability to make definitive attributions!

In any event, I'm glad I got it but also glad it's done. Thanks for your support, all.
