This thread sure caught my eye. I also suffer from pelvic floor dysfunction that has gone in and out of remission since 2003. When it came back last year, I was in agony! I went to a female gyn. pain specialist at Stanford who said it seemed to definitely be muscle related and recommended pelvic floor rehab. I went to a great rehab center in San Francisco, and after three months, the pain was almost gone. I am always on the look out though for a relapse. I can't tell you how devastating it was to go through an agonizing condition like that and get so much better, only to be stricken with PN afterwards.
