This is a nerve itch , ive had this and it just about makes me scream ,it will move all over and you cant get rid of it some times it bothers me so much, you are maybe putting on a shirt or some thing that rubs the nreve wrong and makes them all react, or its you bed linins touching some where and making it start, what its doing is travling around circuit in the nerve line , and it feels like it crawls under the skin, when its really just one nerve thats transmitting the itch, it should leave after a little while doing this , if you can have some one touch the right nerve then you can figure out the one thats causing, this , and cover it with a pad for a day or two to let it rest, then it will be ok, up in the base of the skull is a lot of nerve endings , and of corse the spine, so have some one press in , and try to find the nerve , if not go to the doctor or just wait and it will go away
