Vulva irritation

Hello, I have been having irritation and itching on my vulva area for over two months now. The inside of my lips are also red. After seeing my Gynocologist twice we have ruled out a yeast infection and BV. I have been on two different steroid creams that helped some but it still driving me crazy. Any thoughts? It just started out of the blue. I havent changed any of my products prior to this irritation starting. I did change our laundry detergent to fragnrence free as well as my body wash to an unsented one, to try and help the irritation but no luck. I also am wearing 100% cotton underwear. Hopefully it will go away on its own. thanks

hey are you burning or anything ?
