I have had RSD for four years now and have been diagnosed with osteoarthritis in both hips; severe in right, which is side originated in on me. Am allergic to most pain meds, orthopedist recommends hip replacement, as rt hip is bone on bone, but pain dr says no due to risk of flare up from surgery. Pain dr says rsd doesn't spread without another trauma and just wants to pump me with meds and injectioins.. Anyone have any advice?
