Is anyone else familiar with these pains?

I'm 37w 3d pregnant and every single time my baby moves the opening of my thigh lock up and I'm in excruciating pain. It's like I'm getting a Charlie horse times 10. It happens mostly when I walk or standing up for a minute. (Like mall or grocery store trips) I don't know if it's suppose to hurt this bad every time he does a big movement.
