Ow!! Sharp pains like a knife??

Sometimes out of nowhere I'll feel a sharp pain in my vagina or in between the butt and vagina. Sometimes it'll hurt for longer and I'll be in some real pain like I can't move. It's like it paralyzes you for a tiny second 😬😬😵 google doesn't help much, it's like oh maybe you're gonna die. Sooo anyone have any comments/ know what could be happening here?
