Yet another nurse with CRPS that smokes-yikes!
In my experience, smoking does help me with stress at times, though I know that in the long run it costs me in circulation to my CRPS left leg. Yes, it discolors. During the times that I had a SCS done and a subsequent revision, I had to cut down on my trips to the garage (my hubby does not smoke and I don't do so in the house because of our children, though they certainly know what I'm doing out there), but I still made it out there at least once or twice a day. It's a crutch...but we all have one.
