I also have low pelvis pain. For the past 6 months it has been almost constant during the day. It used to be mostly the right side but now it's also the left and the very lowest part of my back, right above the buttocks. I think that must be a nerve. At this point, nothing is helping. Peppermint tea, Ginger Aid tea, chamomile. I'm getting very used to it and hope it goes away as suddenly as it appeared.
