I don't have RSD. But I do have small fiber PN or central sensitization. In any case neuropathic pain along with some radiculopathy. I had facet injections done at L4/L5 and S1 over a year ago and then an RF. BEFORE I had this done I asked my Neurologist if it could make the PN worse, she said no and to go ahead. And she along with my PM explained that it is a medial branch nerve that is ablated...NOT a motor nerve. So, I had it done and it worked beautifully for a year. The nerves do grow back but you can repeat the procedure if it is painful. I want another one done since it has been way over a year and I know the nerves have grown back. For RSD people I am just not sure but it something you certainly want to discuss with your doc. I am just not sure what nerve your doc would want to ablate. I would find that out first.
