vulvodynia pain

does anyone have vulvodynia? I got it a few months ago and no one knows why. it's excruciating pain on the outside part of the vagina. I also have burning mouth syndrome. fibromyalgia and costochondritis. I am at the end of my rope from pain. my life has become small, and all I do is try to get out of pain 24/7. I can take tramadol, but am so afraid of addiction and dependence..
This is all very discouraging and I just can't handle it much longer.
