It's not herpes. Herpes produces a ckuster of blisters, which last 7-10 days and go away (though they may recur.) What you are describing is irritated skin after trauma. The Elocon was a good thing to use, because it reduces inflammation. What I would do now is nothing. Leave the area alone, and cleanse as you would anyway. Then show it to the dermatologist in February for definitive diagnosis. Meantime, look up herpes at http://www.dermnet.org.nz/index.html, and don't worry. Also, don't pick at your scrotum, with or without your fingernail!
Best.
