I can only share my personal experience with you. I had bilateral calcaneal fractures, my right foot was all but a thread attached to my lower leg. It was a crush injury, I severed the tendons, artreries, and nerves along with many other smaller implications as well as compartment syndrome in my right foot. My left foot had the same crush injury but was not an open fracture. So, I have CRPS type 1 in my left foot and late stage causalgia in my right foot. Both of my feet and lower legs are very painful, however, there is a major intensity in my right foot that is really indescribable compared to the left. But the injury to my right foot was also much worse than the left. I also deal with alot of postraumatic pain and deformities on the right that I do not have on the left.

So in my personal experience, the CRPS type 11 is a more intense pain due to the nerve damage. For instance, normally I can control the pain in my left foot with medication, TENS Unit, etc. But the right one, I have no control of the pain, ever. I don't know if this was the insight you are looking for, but by having both, I can only tell you the difference I feel between both feet. They can call it whatever they want, or list it in stages, but pain is pain. Hope this helps. Best wishes.
