The Sciatic Nerve

What is the sciatic nerve? Well, it's an evil nerve in your body that is intent on ruining your days when you are pregnant. When Liam positions himself in a certain way, he ends up on this nerve, and I literally can't walk. I can be in the middle of walking and then I suddenly fall. It's really fun to fall for no reason (I'm not falling down to the ground, just stumbling). I enjoy having people look at me like I'm a complete weirdo or, even worse, a drunk pregnant woman. Eventually, Liam moves and I regain normal movement, but I am really considering calling life alert. I need a button that says, Help! I've fallen and I can't get up! (except I'm not 85, which makes this even more depressing).
