Thank you, DG and Mary. This has definitely reared his head during the past few weeks since taking a break from the HRT, so I'm definitely going back on it. I found out what I wanted to by taking the break, that I still had a natural period, so I don't see the point in suffering and certainly don't want full-blown VA to set in. I'll see how it goes for the next week with the resumption of the HRT and ask my GP if she thinks a course of Vagifem is worth a go, next week when I see her.
Got some Multi-gyn so will use a bit of that in the meantime. Thanks again ladies.
