Sorry if TMI but genital pain with chemo...

When did you start the Olive and Bee?
Could you have an allergy to that?
I would really ask your Oncologist, as I don't remember that on the list of possible side effects.
Vaginal Atrophy, is a thing with normal Menopause, and even worse on Aromatase Inhibitors. But I doubt you have started these as yet. Vaginal Atrophy is when the tissues in and around the vagina become pale, thin and less lubricated. This can be painful, but doesn't quite sound like your description. 
I hope that you get an answer to your problem soon. 

hi @MillyMollyMulberry that sounds really awful for you ❤️🌻🌼
Good suggestions from others to mention it to you bc nurse and oncologist.
Might it be thrush? During the first couple of chemos I had thrush in the mouth and under one of my breasts. 

Hi there, I have not experienced this but I suggest talk to your oncologist or breast care nurse today. It doesn't sound right and maybe you need some treatment for it. Best wishes 

Sorry to hear this @MillyMollyMulberry - have you told your Onc?  It almost sounds like an allergy to your treatment?  They may have heard of it happening to others?

I think there may be more members affected with vaginal atrophy than swelling such as your description? 

I hope you can find the cause and get some relief & fix it xx

take care
