Got hit by a rusty nail

Hi there, I'm trying to calm down but it's really getting under my skin this past days. So I walked on a rusty nail(not a deep cut) and I clean it immediately with hot water and after 2 days I got a td shot in my arm and I was told it's enough. But yesterday and today I feel like my right cheek is kinda heavy. I don't know if my mind playing me or there is some pimple there that gives that impression and I'm freaking out. Do I need to see a doc after the shot? Is it enough what I did until now and I need to forget about the situation ?
