My RSD has spread hands, arm, shoulder, scapula, feet, leg. Taking Lyrica, cymbalta, lidoderm patches and oxycontin. Spreading continued so Dr. stopped oxycontin and started Methadone. I was upset about narcoticsl, but FINALLY my pain has decreased, less sensative, not turning purple constantly, walking is easier! I am so happy. I guess i have to just except the fact that i have RSD and i may need to take medicine that I dont like but that helps me. I still do epsom salt baths or foot baths which really help. Hope this helps someone else. momof4
