atrophic vaginitis
"I had extreme pain during intercourse and also experienced severe atrophy.  The Estring provided a miracle solution.  I have had no side effects, except a little weight gain. My vagina seems to be more lubricated and intercourse is no longer painful.  I am wondering if it is okay to go in a hot tub and take hot baths with it.  I have not found the answer to this question anywhere."
