You would'nt think it would consistantly??? But I have a siatic nerve problem on a regular basis starting at about 16 weeks, it seems to happen when i lean forward and then it hangs around for ages, it probablly is your body adjusting to all the changes and ligaments softening, do you have any pains in the front? maybe you are just getting them in the back area. My bubs is a cellar dweller and stays low a lot of the time, she is starting to give me good kicks in the bladder /f*nny area which are uncomfortable and not so nice but not painfull, keep the brace in mind, you might benefit from it.
