Hi Yvonnepi, so sorry to hear about your pain. What cream are you using and how often? Have you been checked for anything else other than infection? (Skin conditions or pelvic floor dysfunction, for example.) Have you had a look to see if there is inflammation or any lesions? Vulvodynia is just an umbrella term for pain in the vulva, so there could be any number of causes.
Jane Lewis's private Vaginal Atrophy Facebook page is a good place to discuss your symptoms and perhaps get some answers.
