I am not sure if I should be concerned or not. I had my second vaccine (Pfizer) last Tuesday, felt a bit run down for a few days but feel OK now apart from the arm that I had the jab in has become hot and swollen about 5 inch below the injection site. It's only started today, it's not painful but I can feel it (if you know what I mean).
I don't know if to bother 111 or not.
