Hi ,I was just trying to get information out on a fairly new Med the Oxymorphone ,which woul;d be the natural step above Oxyconton but it is whatever the patient deems best ,we all have gotten RSD in different ways ,it affects each of us differently ,I tried the Ketamine but never again ,in my nearly 39 years since my RSD was dx ed ,I have tried just about everything and now I take my Morphine Contin and Morphine IR ,if your state allows Avinza it is the best Morphine I have taken and is on the Tennessee Formu;ary for SSI ,it is made differently but it didnt last 24 hours with me soo I took ot QID,my pain was helped more than ever before but here in Oregon it is too expensive and I am lucky to get the Purdue Frederick Morphine Contin ,IO am glad that since people are diverse so is the way people can be treated for this horrible disease we have ,I wake up in fear of the day each morning but get through the day still ,I wish you al;l well Gentle Hug
