Good catch on the NO ICE. Forgot to mention that.
NO ICE!!! Never! Plenty of research to back up this recommendation.
Many doctors that aren't up to date with CRPS may recommend icing. Don't do it. It seems like it might help what with "burning pain", but it will do more harm than good.
Here is a link that contains much good information about CRPS. It is a bit dated, but still very relevant. Good luck!
