Don't know how to explain it but sometimes i get like a ticklish/ buzz feeling in my head that last's like 1 sec, but it comes and goes, anxiety mayb?

Research yourself: Sometimes when a person is having a strange, transient sensation, the best thing to do is carry around a little notebook or use your cell phone and whenever you experience that sensation make a note of things like day, time, where you are and what you are doing, etc, looking for clues that might indicate a cause. What may not be obvious in the moment may become more clear with data over time.
