I'm not sure why you're experiencing that, but it sounds like you could try a massage to get circulation into your head? It might just be blocked nerves. Your neck may be in need of a chiropractic adjustment too.
I have a spot on my right foot on the side of the heel that I have to avoid touching. It sends out a web of tingleing, almost electrical feeling, every time. It isn't painful, just a sensation I'd rather not feel. I have no clue what caused it. My acupuncturist couldn't figure it out either. I'm hoping it will eventually correct itself.
