It might be a partial blockage if you had a BM. I know I've had one a few hours before my blockages have taken 'full effect' so to speak. Painkillers have been useless in that situation for me though. That is, until I went to the ER and got a morphine injection. I think if the pain doesn't go away, and/or you're not passing anything I would at least call the doctor's office. A nurse could tell you what the best thing to do would be at that point.
I hope you figure out what is going on...I'm sorry you're going through this :/
