Ha!
That was my first thought reading the thread title and subsequent post. There's something to be said about this though. I have a side effect from cancer treatment and surgery called Lhermitte's syndrome and it's exactly that feeling. Sometimes when I look down I get what feels like an electric shock feeling that goes through my spine and into my arms and body. Not saying it's that but it is caused by that maneuver and a rather common feeling associated with bending your head forward. While weird and somewhat unsettling, its totally benign. Just try to avoid that movement is all.
