I am so sorry for all you are going through. My eyes are effected as well though I am still not sure if it is rsd but every other specialty and condition has been ruled out. My major rsd is the foot/inner ankle/calf. Anyhow though not as bad as your results but my nerve block made me way worse too. I had looked into the op ketamine but right now am working with oral meds since the scs had been ruled out and the lidocaine infusion made me worse as well. There is another girl here who has ketamine and I think has gotten help from it. She goes if I recall to LA. If you do a search it may come up. I wish I had more direction and answers for you. As you know we all respond different and is part of the frustration. Are you currently on any oral meds for now? Hang in there and sending better thoughts
