I had the infusion in January. Had my first Moderna injection 2 1/2 weeks ago. I was so sick the next day, I feared I was getting COVID again. That lasted about 48 hours. Then, the injection site had a terrible reaction. I had a red, rashly welt, bigger than a softball for a good week. It hurt, was itchy & looked awful. Google moderna arm or COVID arm. My arm still has a red circle, about the size of a tennis ball, but it’s flat and dry and doesn’t bother me. I am set to get the 2nd dose next week, & am nervous, but hoping for the best. I still have numerous things happening with what they are calling Long COVID, so am hoping the injections eliminate those symptoms.
