Yup.
I haven't officially been DXd with DH, but I'm 99% positive that's what it is. I've had it since childhood. It's maddening - both itchy and painful.
I often get it on my neck right up near the hairline in the back (that's where I always got it when I was a child and teen) but now I also get it on my face at times. Sometimes I get it on my back...
