I saw one of the top specialists and he was shocked that anyone had tried such an "old-school", ineffective technique on me.
Today I got a vestibulectomy.
The vulva is gridded and then injected with steroids and lidocaine to flood the skin and to get at all the branches of the nerves. I had this as my "last hope" before a serious consideration of a vestibulectomy. Had it worked, even a bit, I could have had it done once again. I did not find data on its effectiveness, but the doctor was optimistic, so I tried it.
