The swelling in my main RSD site (rt ankle) is almost non-existent now, but it's still very painful. I still have a purple/mottled appearance over the whole foot, but no swelling or discoloration in the knee where it spread after my ankle. The secondary spot (my lower spine) still has some swelling, but no discoloration or temp change- lots of pain. I think the issue is that like any disease, people experience some of the symptoms at one time and other symptoms or all of them at others. Stick with oyur treatments and keep your doctor informed so he/she can help you out. Good luck!
