What does this mean

Okay so me and the guy I'm talking to have done shit and the 2 times he's fingered me last time my clit became really swollen and it hurt and then when I peed it burned a lott and then the next day my clit went back to normal and I peed all day perfectly fine mind you this was yesterday and now today the same thing happened, what does this mean? That he's maybe going at it too rough? Or?
