Really worried!

I was masturbating yesterday quite a lot and quite roughly. Today I was going to masturbate again, but I noticed that my clit looks swollen and black. I haven't looked at my clit in awhile so I don't know if it is normal for me. I know these things change when you're young (which I am) but I don't know if it's normal. More worrying, though, is that there is a painful lump on my clitoris hood above it and to the right. It looks a little purple and is a little larger than my clit. I'm really concerned. Sorry for the long post.
