in the still of the night

I woke up in the middle of the night with a terrible charley horse. Not in the calves or quads, but in the levator ani (https://en.wikipedia.org/wiki/Levator_ani). How do I know this? 1) I am a physical therapist. 2) I suddenly had to poop really bad. But in my state of delirious pain, I was still able to rationalize and figure that I didn't ACTUALLY have to poop, but because of the pelvic floor spasm, afferent nerve signals were probably being sent up to my brain trying to tell me I had to. Nevertheless, I went to the bathroom just to appease my confused pudendal nerve, and squeezed out a tiny poop. The charley horse was so bad it literally cramped the shit out of me.
