vulvodynia and skin thinning

hi everyone. just saw the vulva specialist who formally diagnosed me with vulvodynia and vestibulitis. if you have seen my previous posts you can see the symptoms ive been dealing with. When i went to my appointment he noticed i was very thin in the fourchette area and during sex it erodes everytime. he prescribed me a topical estrogen cream for that area. anyone deal with thinning, erosions, tearing etc with these conditions? im only 19 btw so its not menopause
