atrophic vaginitis
"The estring was my answer to vagina dryness and extremely painful intercourse. And I wasn't even in menopause yet.  I also had vuvlydynia causing extremely burn and pain.  I had tried the cream, Estrace, but could never keep it up and didn't want to deal with it.  Finally  my doctor recommended the estring.  After 2 or 3 weeks, I was feeling completely normal again.  I've been using this for almost 9 months now, and I no longer have any pain, and the vuvlydynia seems to be gone.  It's a miracle.  I can actually have pain free sex once again."
