Interesting. My wife has had RSD going on 11 years now and hers has changed. I can not express the pain she had in the earlier days. She had very bad reactions to meds like Lyrica-cymbalta. It took her years to get a diagnoses and took very strong narcotics for at least 5 years. Her pain has changed. She describes it as deep in the bone pain through-out. The difference now is she takes no narcotics. She is clearly in pain and everyone can see it in the way she moves. Those who don't know her can see clearly something is wrong, but her need for narcotics at this time is so much less than those early years. Is there a such thing as RSD burning out, not sure. I once read a Scandinavian research paper on RSD that stated females who are past menopause have a good chance of remission.
