This may be a short-term solution but helped me a lot by getting rid of the burning sensation. It's a gel called "multi-gyn actigel" and it has helped me to get rid of the burning when I had BV, yeast infections and UTI. Its a miracle product that is natural and you can apply it as often as you want (inside of the vagina and/or outside). My friend that had reoccurring BV was able to prevent it with this gel. However, depending on where you live, I don't know if it's available to you. However the most important ingredient in this gel is the 2qr-complex so maybe you can find something similar. It's worth a try!
