Hi Linda
Your worries about using estrogen cream will pale into insignificance when your VA becomes chronic.
I refused treatment at first, I was like you but when it got to the stage of being crippled by this nasty condition, all worries went away and after nearly a year of treatment I am so glad I took the treatment and I'm doing very well on it.
As VA progresses, as we age, you will find it impossible to live with, it’s such a safe treatment and the sooner you start it the better.
I haven’t noticed any side effects just so glad there is a treatment for it.
