OH YEAH! I am very familiar with this one! I get this sort of buzzing bee feeling, but it's all over inside my body. Once and a while, I will get it in one specific place, say, my arm or leg, but mostly, it happens all over inside. (esp. around the chest and abdominal area). I can have this for two days straight, or sometimes, just for a few hours. However, this is a very strange feeling, and makes me very uneasy. It literally does feel as though there is some sort of "thing" buzzing inside you!
WHAT NEXT?..lol..

(oh wait, have any of you had this in your head? I have!)
