How To Cure Vulvar Pain ?

I have had vulvar pain for about 2 years now. My symptoms are mostly unprovoked and provoked pain in the vestibule. My biggest conern is the horrible pain I suffer everyday in my vestibule. It feels like someone is pinching my tissues down there. I also have unprovoked pain outside of the vestibule sometimes. Also, last week I experienced intense pain in my tailbone and sit bones while sitting at my dest at work. This has for the most part subsided but the fact that it happened concerns me. I have no idea what my problems is. HELP!! The pain is so scary.
