Hi Karen max

Sorry to hear about all your problems.
Were you prescribed the anti-depressants and propanolol for menopausal symptoms ie after your periods went wonky and you started to get symptoms, and in the absence of any previous history of depression? If so your doc was quite wrong and should have given you HRT and kept trying different preparations until you found one to suit you as ADs are not the first line of treatment - even for menopausal low mood.
In the meantime yes you can get estrogel or sandrena on NHS as well as oestrogen patches. Personally I prefer these ( patches) - Estradot are good because they are very small - and changed twice weekly. Gel is applied once a day - matter of preference really. You would need a progestogen and ideally even though postmenopausal it's better to start it cyclically so that you can get used to oestrogen only and how you feel on this regime. The usual one is Utrogestan (micronised progesterone). You will need to be firm with your doctor if you want to try these products - they are all available on NHS.
You do not need to mention "BHRT" but if your doc tries to refuse to prescribe what you ask for, you would need to say you want to use hormones that are identical to those your body makes ie they are "bio-identical". BHRT is the term that is generally used for private compounding pharmacies - which prescribe"Bioidentical Hormone Replacement Therapy" but is not generally recommended as such.
I hope this does not sound confusing?
Sadly if you are still experiencing symptoms after 4 years since menopause, you may be one who continues to get flushes for many years - some women do - in which case the sooner the better to start HRT. The good news also is that after your op you only have to take oestrogen as it is often the progesterone which causes the problems but having ovaries out too is a bit more drastic and sometimes takes a little longer to find the right dose.
It might be worth trying to find something sooner than later if the waiting list is long - so that you can experiment and at least find some relief in the meantime?
