I can sympathize with you. This happened to me several months ago. I would wake in the middle of the night with my neck itching so badly I could not sleep. I tried to think of anything that I had used differently or anything I may have eaten unusual. Nothing seemed to make a difference. I thought I was going crazy since the itching was confined only to my neck. I got some relief by using cortizone creams;however, the condition (for whatever cause) cleared up on its own. I wondered to myself if hormones had anything to do with it. Best wishes.
