Leah, one of the post op women in a fb group I am in also suffers such pain, though she seems a great deal worse off than you. She is 6 months post op and has spent the majority of that time in hospital. The surgeon, and a urologist could find not medical reason for her pain, so she was referred to a specialist pain doctor. He diagnosed her with Neuropathic Pain, and has had some success with medications, but she is not cured by any means.
See your surgeon, and get them to refer you to specialists if the surgeon cannot resolve the pain. During our operations, many nerves are cut and sometimes sutured nearby, but this type of pain is expected to settle. I also know of a woman whose clitoris was not protected by a hood, and she was in a lot of pain from underwear rubbing. I really feel for you are we undergo surgery to relieve pain in our lives, not to encounter pain of a different kind.
Hugs,
Allie
