Treatment for Bacterial Vaginosis treatment cured my smelly underarms

I have tried for many years to find a deodorant/ solution for my smelly underarms. Nothing ever worked. Or it would work for a few months and then stop working. Coincidentally, I also get BV frequently and often. I have recently realized, that when I use boric acids suppositories to treat my BV my underarm odor disappears (not completely) but enough that I can use regular deodorant and not have to worry about it not working. Have you heard of this before and what is the correlation between BV and underarm odor?
