I take magnesium which was suggested by Mrs D and then restated by the holistic doctor I saw. I also take now klonopin and I think zanaflex for muscle relaxing and am on a similar drug to Lyrica neurontin though it does not help with sleep. I am so sensitive to cold to where it turns me into crying pain from the frozen foot/ankle which increases pain. Also for a supplement omega's help with inflammation. My rsd pain doc also suggested the vitamin c. It can take time to see results with meds so try to hang in there. Is there something you can take more as needed in the terrible flares? Many thoughts
