Hi, I Am A Man That Had A Slick And

Hi, I am a man that had a slick and stinky something in the creases of my legs. I thot it was a yeast infection and put some monistat 7 there at bed time. I woke up with a dime sized knot on my right testicle. I mashed on that and got a lot of blood and puss from it. but some time later, the swelling came back and my pubic area hurts a lot. What shall I do. I don't have money to go to a doctor. I am not in a relationship with anyone and this is not a result of masturbation. I have been taking some vitamins A, E, B2
