Hi, I Am A Male Teenager Who Started Having Bad

Hi, I am a male teenager who started having bad itching all on my inner thighs and a couple months later it has worsened to these weird nasty/creepy scarring patters all down my inner thighs from the groin to about 3/4 the way to the knee. Now I am experiencing some itching rash like patches appearing on some parts of my thighs and now the dark scars like patters are starting to appear everywhere on my thighs. I have tried some jock itch creams and I also cant find any pictures of the scarring online.
