Hi. I am sorry for your injury. I have RSD not from an injury though the cause is unknown and I have PN too. I was dx with both around the similar time though PN was first. My pain doc did suggest taking vitamin c for repair too. I agree I think with Mrs D who said we are more sensitive. Even my areas that are not impacted if I knock it or what ever I seem to be more sore then pre these conditions. Hope you feel better
