Drifting,

Welcome to NeuroTalk.

Itching often is caused by a change in blood flow or inflammation. I have had the left side of my head tingle and/or itch from time to time for years. It seems to happen to me in clusters. After not experiencing it is a long time, I forget when the last time was, it started up again last week.

I have learned to just ignore it since I have never been able to stop it. But then, I have never had it real bad.
