Can you please define out of the box?
If you had to live with your RSD without any medications, you would find a way I guess. I have a friend in Australia that suffers through and has some great people working through more holistic ways to cope. It is not a cure and it is not a remission, however, I can maybe get you to her if this is what you are needing. Right now, she is working with Mirror box stylings and foods to assist in flares.
Contact me off group, and keep in mind, that this might not help you. She is really the expert though and I can check with her, if you would like...
Hugs,
Rain
