Hi Kitz,

I was just talking about this type of "pain in your bum" with a lady the other day, the way I describe it is it feels like if you could just do a big F**t it would feel so much better LOL. I do remember having a simular poping sensation sometimes when weeing but I don't remember it being painful.
It would be interesting to hear a medical explaination for what is going on. Hopefilly someone will come up with some answers.

Not long now for you, best wishes for a great birthing experience.
