I have Sjogren's and two of the symptoms of this disorder are mouth sores and vulvodynia. My mother also had this and now one of my half-sisters, as well. I had severe mouth sores for several years and none of the dr.s or dentists that I consulted (at least 7) had any idea for this. I discovered 1st that it's common with menopause (why don't doctors know this???) and that taking Vit. B 12 daily has made it normal (unless I eat walnuts, raw pineapple, or strawberries which my allergist says are all extremely acidic and affect the mouth.) Perhaps that would help you; I take the ones that dissolve under your tongue and also Vit. D3 liquid drops as well. For vulvodynia, (also called Burning Vulva) my sister uses a hormone cream in the vagina; because taking Hormone Replacement Therapy triggered breast cancer for me 20 years ago, I keep my own vulvodynia at bay with one of the oldest SSRI's (Selective Seratonin Reuptake Inhibitor) called Amitriptyline) and it keeps this from causing the pain I had without it. I hope you have some relief from the pain soon!
