Head shock (similar to funnybone)
I'm hoping someone can help me.
Since I can remember, every now and again at a spontaneous moment, I get a very painful but short(few seconds) electric shock (likened to a funny bone sensation) from the base of my head to the top of my head (left or right side it varies).
I can get them anything from a few times a day to a few times a month to one in months.
It's quite painful and makes my head involuntarily jerk.
There is no pattern at all to this. The last time I got it though (about a week ago) the shock went throught the left side of my head but my ear was tingly/numb after (this was a first).
I'm wondering if anyone knows what this is or what causes it or possibly experienced something similar themselves.
Thanks for your help!
