Estriol Cream for vaginal itching???

My doctor prescribed this and I really don't know why. I may be going through perimeno, and am getting a saliva hormone test, but I don't know why she even prescribed it. I told her I wasn't "dry" and when she said "atrophy", I said, I don't have that either. After researching it, it seems as though it is primarily for dryness which I don't have.
I've had vaginail itching and irriation, due to desquamitive vaginitus, and yeast infections in the past, but for months, cultures are all normal, everything is normal.
Has anyone used this stuff? I don't think I need it. Tweet
