Thanks for this Daylily! Interesting. So, my spine surgeon never really came out and told me what happened . I figured out for myself that I had CRPS based on tons of internet search. However, after reading about the Central Pain Syndrome I wonder if that applies to me? I had an Artificial Disc in my spine that broke, and the metal was migrating towards my spinal cord. It was an extremely difficult surgery to get the broken device out of my spine, and I woke up with the CRPS monster in my bed (HaHa). I have "painful numbness" in my right foot and ankle along with the temperature changes, skin color changes, burning sensation, sharp stabbing zingers & muscle atrophy. I haven't heard anyone else here say they have the painful numbness as part of their CRPS. Now I see it in the description of CPS, so I feel more confused
