Should I go to the doctor?

Hey guys, I’d normally not ask such a question and instead go straight to the doctor but where I’m currently living they tend to get a bit pissy if you bother them with something they consider unimportant, so here it is - two months ago I got a rash on my hand that went away in a couple of weeks (rash started after playing beach volleyball so I thought that it was just irritated skin). Since then the rash has been replaced by this big red spot that looks like a pimple and it’s kind of itchy. Have you ever experienced something similar?
