Thanks for sharing your photos. I have the same spots on forearm, diagnosed as senile purpura, but oddly, they only began to appear several months after my first Covid Vaccine. I never had them before. I don’t believe it’s a coincidence because after first booster they appeared the next day, mostly on left forearm where I received the dose, but also sometimes on the right. I have tried to research the connection, but haven’t found anything similar. They most often appear unrelated to physical activity, but I also notice now if I scrape my arm even slightly against a surface, they immediately appear. Sometimes large patches, other times tiny, multiple dots. No pain or itchiness. I had no other side effects from the shots. I have asthma and take inhaled steroids so wonder if the combination set it off. I would be grateful to learn if anyone else has experienced or heard of this reaction. (I did fill out the “adverse reaction” paperwork for Pfizer, but had no response.) I am not against vaccine and grateful for it as I live with an elder parent, who is vulnerable, and need to protect her as much as possible. Thank you.
