An unusual area to have CRPS

Hello, this is my first post on Reddit. I have been trying to read and find someone that has CRPS in the same location I do. I see that the common areas are the extremities and it travels from then onward throughout the body in some ocassions. However, my localized pain is in the entry of my vagina. I have other medical conditions, however this seems to be the most puzzling for my physicians. I have tried nerve blocks, topical analgesics, and numerous over the counter medications. Is there anyone else that has the condition in such a delicate area and have seen results?

Because I have seen no such positive results, only negative and I am going on having pain in the entrance for going on ten years and I am currently 24. Is there anyone out there with a positive story that can give hope?
