See mine is a bit different, mostly a pulling, and sucking sensation at the top of my head.

The only area that I've felt a ripping or stabbing sensation is either on my wrists or the back of my knees, something was trying to rip my veins open, that sensation had me nearly in tears the times it's happened, cause it felt weird and hurt. I don't get it much of as bad now that I'm on meds, so that's good...
