i think ldn is still in its trial stages for rsd but not sure. if i were you i would do your research on it before trying something new that is new. maybe it will help but the thought of going through such pain for so long waiting for it to work sounds like more then i could bear. and i would think that could aggravate the rsd more. but everyone is different and i am not a dr so i would check with several drs about this new drug. hope things get better for you soon purplefoot.
