So sorry to hear it did not help you. I'm told a big difference in success rate is whether you were in "proper position" prior to the injections. Here in Charlotte, those I've consulted with told me it wasn't necessary to be in proper position. . . but they only had at most 50% success rate. A doctor in Atlanta has a 98% success rate, but he is adamant about a PT being present to assure proper SI joint positioning prior to injecting.
