This started 6 months ago after a one night stand with a girl. I dont know if it was the sheets in the hotel or the girl.

My testicles are really itchy everyday, ive tried hydrocrotizone cream, rubbing alchohol, lotrimin, cefalexina 500 mg, scabbies treatment and non of them have worked. And also my legs and butt cheeks are really itchy every night but it seems like something different from whats on the testicles because when i scratch my legs or cheeks it turns into a really bad red rash, the skin gets really inflamated and red.

I dont know but this is driving me crazy, i havent been able to see a DR because of work and I dont know if i should see a skin DR or a dermotologist. But i am going to see one in the very near future but what do you think it could be.
