I have eczema in the same place you mentioned...the back of my neck. It began as a tiny patch when I was a teenager, but now I am 29 and it's much larger. I am thankful that my hair keeps it hidden, but I fear it growing more. Sometimes it itches so bad it feels like my skin is on fire. I was given Arbonne vitamin C skin products to wash with twice a day...this is reducing the itching, but I know this is a problem on the inside....is anything working for you???
