Vaginal Health :: Red Burning Vulva

I've been suffering from a vagina condition for almost a year now. It started out with what seemed like a yeast infection with painful burning inside and out but after many courses of antibiotics, steroid cream, antifungal, my condition down there has only worsened. I have even been on vagifem because my dermatologist said estrogen was low on the skin down there maybe due to being on birth-control for so many years. Stopped birth control stayed on vagifem, no improvement. My parts are now constantly red and burning inside and out and she said I have Vulvodynia because she can't explain it. I've been in vagina therapy and taking an antidepressant so suppress the nerve endings. I only experienced a brief 2 week period of relief before it came back worse than before. My doctors can't figure anything out, they put me on hydrocortisone cream 10% intravaginally for 4 weeks, then clindamycin cream again, no improvement. Nothing helps the pain except epsom salt bath soaks and ice.I'm scheduled to see another Gyno for hopefully a pair of fresh eyes on my condition because so far no doctor has found a helpful solution. My boyfriend and I do manage to have sex once a week but it's always painful and we have to use lots of lube because I get very dry which is why I keep thinking it's estrogen related but I'm only 31. I've been tested for STDs and all that jazz, he is the only sexual partner I've ever had and prior to us beginning to have sex, I never had these issues in my life. They didn't happen immediately, I didn't start having this problem until 3 months or so after we were having sex, first with condoms than without so, I dunno. My mom said she would get yeast infections all the time when she had sex with my dad but my doctors never find evidence of yeast in my cultures or really anything except that my parts are clearly inflamed from my white cell count.I'm at my wits end with this, I can barely enjoy sex anymore or get in the mood. I'm always uncomfortable. I no longer shave down there, wear all cotton panties, sleep without underwear at night, take daily epsom salt soaks. My boyfriend and I did stop having sex for a few months to see if that helped but it didn't. Sex does aggravate it though but so does moving around, driving and sitting, sitting is the worst. The skin down there is red all over and it hurts to rub my clit or touch down there and it just burns all the time like its on fire. Its awful, anyone had anything similar to this?I've tried home remedies too, different soaks, herbal supplements, cut out soda and trying to eat better diet wise. It also burns when I pee sometimes but not all the time. I think it burns cause the skin down there is so inflamed that anything that hits it just makes it scream in pain. I keep thinking it has to be autoimmune or an allergen I'm not aware of even though I use unscented soap, shaving cream etc.
