Edit: I WAS CURED AFTER 22 YEARS! I had a vestibulectomy Dec. 2016. The recovery was easier for me than having sex ever was. It took about 5 weeks. I have included my recovery photos. Look for the blogpost "I'm Cured!" and "My Vestibulectomy".
I’m a great woman with a pissed-off vulva. I have “primary vestibulitis." Most people are uncomfortable discussing their genital pain in public. My hope is that my obsession to find help for myself will make your experience shorter, easier, and less painful. P.S. Recently "vestibulitis" has been renamed to "vestibulodynia."
The book is for self-help with excellent diagrams and photos and focuses on exercises to relax and strengthen your pelvic floor. It has excellent explanations for what each exercise accomplishes. For example, for someone with chronically tight pelvic muscles, before you can Kegel to strengthen the pelvic floor, you need to learn to relax those muscles. If your muscles are so tight that they can't release and then contract fluidly, you can't develop strength and stability (and avoid incontinence). I use the relaxation exercises to reduce my nerve pain.
This book is really accessible, perhaps the best of my "library" of 12 books, and a worthy investment.
