So I was just cutting up my dinner when all of a sudden my hand completely FROZE in place. I couldn't bend any of my fingers and there was this weird pain going through it the whole time.

I managed to fix it by twisting my wrist around and 'uncracking' my hand but then the same thing happened again a few seconds later before going away. Now I just have a tightness around the area...

I had a milder case of this a few months by when I was in the shower. I just pressed the power button and my index finger went numb for a few seconds before functioning properly again.

Any of you guy know what this could be? I'm kind of scared D:
