Every now and then I get an itchy rash-like patch at the base of the back of my neck.  I sometimes think its related to me having been rubbing my neck, but I cannot always correlate neck pain with the onset.  I dont have a fever, or any other symptoms that Im aware of.  I cant recall coming into contact with anything that might irritate it.  I do have a history of cervical discectomy and fusion (anterior) at C 5-6, 10 years ago, and sometimes get stinging and burning in the area, presumably from nerve pain.  As I mentioned it isnt painful, just itchy and sensitive if I scratch it.
