What is wrong with my foot

Hi. I have this thing on my foot that kind of looks like it could be a spider bite (2 clear looking spots next to each other with each surrounded by a small circle of white (not puss) it is about 1×0.5 cm with a 0.5 cm ring around it where the skin is redish) but it has been there for about a month now, isnt itchy, is firm, and hurts when pressure is applied to it. Im a dancer and martial artist, i dont know if that would have anything to do with this or not
