Hi again sides
Here is a section from an article about atrophy written by Dr Heather Currie in the MM magazine that may be of interest to you:
To treat the underlying vaginal changes due to the lack of estrogen, the treatment that is most likely to revert the changes and restore the tissues to their former health is estrogen. If just treating the vagina and/or bladder symptoms of the menopause, then very low dose vaginal estrogen in the form of a very small tablet inserted with an applicator, vaginal cream which can also be applied to the outer area (the vulva), a pessary, or a vaginal ring which is replaced every 3 months can be used. These estrogen preparations are very effective and are not associated with risks which should be considered when using Hormone Replacement Therapy since they give a very low dose of estrogen which is concentrated in the vagina and bladder. Any vaginal estrogen preparation should be used for at least 3 months before the expected benefit will be achieved and should be continued long-term, perhaps even indefinitely. Many women are only given a short course of treatment and are disappointed when the symptoms may not be fully treated, or may return when treatment is stopped. We now recognise that these changes persist and gradually worsen without treatment and therefore treatment should be continued; menopausal vaginal changes are not like menopausal flushes and sweats which will reduce or even stop in most women at some stage.
