This how how just a little trauma can affect RSD. In April 2011 I had a specialist come to my house to examine me, he used a sensitivity pin,( small gold coloured with a ball instead of a point. He touched my arm 4 ins above the affectd area, pain was excruciating, within 8 hrs the RSD had spread from below wrist upto my elbow.
Please don't let these guys make things worse for you.
REMEMBER JUST SAY NO
