The last 2 days I have some buzzing feeling in the place where neck meets head and 2" (5 cm) vertical in the head. It is not a pain but a similar filing of the one when you close eyes firmly, but deeper inside. It lasts for 1-2 seconds and repeating varies between every few minutes to every hour. It does not feels like the neck muscles but deeper inside.
I had my neck arteries checked with ultrasound a month ago and everything was fine. I have no pain or any other symptoms. It is unrelated to any activity, sitting, laying down of moving my head in any direction.
I had this feeling maybe 6-7 times in my life but without repeating throughout the day. Any ideas what that might be?
