Hi! Consider your Quality of Life against possible risks?
I am sure that someone will be along with advice. As oestrogen levels drop the muscles may become lax = aches and pains. Also the body may become dry: inside and out - skin, hair, deep in the ears, eyes, vagina ......... do read the 'bladder issues' and 'vaginal atrophy' threads. Make notes ;-).
Some ladies would take HRT for ever, once they fine a regime that suits they can get on with Life again: if it's no longer broken, why fix. It is an individual decision, the 1st thing is to get some HRT advice.
Hopefully someone will be along. Has your GP suggested any medications?
