Is the condition of...?

vulvodynia permenant?

Yes usually it is. But they do have new treatments for it help.
Doctors don't know what causes vulvodynia, but contributing factors may include:

Injury to or irritation of the nerves surrounding your vulvar region
Past vaginal infections
Allergies or a localized hypersensitivity of the skin
Muscle spasms
Many women with vulvodynia have a history of treatment for recurrent vaginitis or vaginal yeast infections. Some women with the condition have a history of sexual abuse. Vulvodynia isn't sexually transmitted or a sign of cancer.
Treatments for vulvodynia focus on relieving symptoms. No one treatment works for every woman, and you may find that a combination of treatments works best for you. Available options may include:

Medications. Tricyclic antidepressants such as amitriptyline can help lessen chronic pain. This type of antidepressant may work better than some of the other types of antidepressants, such as fluoxetine (Prozac, Sarafem) or sertraline (Zoloft), for this condition. Anticonvulsants such as carbamazepine (Tegretol) and gabapentin (Neurontin) also may lessen the pain of vulvodynia. Antihistamines such as hydroxyzine can reduce itching.
Biofeedback therapy. This therapy can help reduce pain by teaching you how to control specific body responses. The goal of biofeedback is to help you enter a relaxed state in order to decrease pain sensation. To cope with vulvodynia, biofeedback can teach you to relax your pelvic muscles, which can sometimes contract in anticipation of pain and actually cause chronic pain itself.
Local anesthetics. Using medications such as lidocaine can provide temporary relief from the pain.
Topical creams. Creams that contain estrogen or cortisone can help alleviate the pain.
Sitz baths. Bathing the area around your external genitals and buttocks in a saline solution can sometimes help make you feel better, but it also has the potential to aggravate your discomfort.
