Is It Possible to Feel Your JP Drains Move Inside Your Belly After Tummy Tuck?

I had a tummy tuck without muscle repair on 8-27-13.There is no sign of infection on either the incisions or at the site of JP drains entrance.There fluid output is decreasing daily, but since then I have noticed that when I move a certain way or take a deep breath I can feel like a clicking 2" above my incision. Also when I am gently massaging my belly I can feel the same clicking. So my question is, is it possible to feel your JP drains move inside your belly? Thanks
