My massage therapist told me he thought I had CRPS/RSD in my right leg because it was colder than my left and from my complaints to him. I went to my PCP and showed him both of my bluish/molted/reddish legs that occurs when I stand and described all my symptoms. The PCP measured my right thigh and said it was about 3/4 inch smaller than the left but felt that was within normal range of differences between sides. He told me that he didn't think I had RSD. So almost another 6 months goes by with a couple more times me mentioning to my PCP about my legs. Finally, I decided to show my pelvic pain specialist my legs and as soon as he looked at them he said to me, "You have CRPS in your legs. How long have you've been having these symptoms?" Then he said to me, I've got to get you into someone who can treat your legs this is not my area of expertise. So I don't think it is uncommon for it to take a while to get a diagnosis.
