Yep, Anonymon...
your descriptions made me grin...they were spot on!
My spasms also have lasted up to 12 hours.
Whimper, flat out cry, accidentally hold me breath (what I do instead of screaming).
Today is 2 weeks on nifedipine/lidocaine. My CRS says he's seen huge, buff guys, weightlifters and football players sit in his office and cry like babies becuse of the pain.
No, you are not a baby. I know the looks though...get brave enough to tell someone and they think you are crazy.
Spasm is not a good word to describe it. Other folks must be imagining it to be like an eyelid twitch.
The worst is the sleepless nights of agony. But, I don't have the "pooping glass" pains that others have during BM.
