I think you should go to the doctor or something... cause that's nasty haha

I agree with the person who very RUDELY haha'd.
Before seeing your doctor, I'd try and do some extra cleaning of the area to see if that helps, just try washing that area a little more often for a few days and if it shows no signs of improvement, go to the doctor

You need to speak to your doctor. Don't worry he/she has heard it all before
