Sharp pain

Anyone ever get like a sharp stinging/stabbing sensation happen in their clit? It doesn't last long and it's when I move around when sitting that it happens. Very rare too that it happens, only every so often. I highly doubt there is anything wrong with me either. I've been checked out by my Obgyn regularly and just know it's not something to be worried about. I think I mentioned it to my sister before once and she agreed with me. What the hell is it and why does it happen?
