I am very interested in this post as I have had the same problem. My pain started on my lower left side about 2 inches to the lower right side of my left hipbone, pain would come and go, usually at night as I was falling asleep. I noticed that the pains have moved to the exact oposite side as well now (right hip bone two inches to the lower left side of it). There must be some organ near the hip bones that is causing this aching sensation. I suspect that the problem is related to the parasite cleansing. I am just finishing up week two in the para gone process. Not sure if I have succesfully completed it or not.... I'm not sure what to do.
