I was wonderig how many others get dicoloration. The other day I was out for a walk in the woods and when I got home my pinky and ring finger on he left had a blue/puprle color that I still have and on the right same 2 fingers are mottled. I learned when I first got TOS learned about the swelling the hard way trying to get my wedding band off so now I wear it on a chain around my neck. But I never did hear anything about such discoloration, I did not bang it or anything it just hapened! Than again it was 15-20s F /6.5-7 C and with the CRPS my hands burn from the cold should see during mid summer in the frozen foods section, me wearing gloves, because the cold make my fingers to burn!
