I Have A "cut" On The Top Of My Butt

I have a "cut" on the top of my butt crack and it's about an inch long. It itches but whenever I try to scratch it it hurts. I also noticed that I have a few bumps next to my butt hole. I have not had sex in about 5 months and even then did not have anal sex. Is this herpes? I am going to see the dr in a couple days but I just want to know if this is something to worry about in the meantime.
