atrophic vaginitis
"Can't really rate Estring properly since my total time using it was about three minutes.  It felt awful.  Removed it and re-inserted it.  Still awful.  Looked at pictures .  Had it in correctly but to no avail.  No way would my husband not feel it.  I could feel it just walking about. I am a petite woman so maybe that is a factor. Some type of applicator would be helpful.  Rinsed it off and put it away.  Maybe I'll try again but I doubt it."
