HRT isn't an instant cure nor will it solve all symptoms for all women. It mayB that you need a hike in dose a few times a week. MayB put the names of the products into the search box on the Forum: make notes ;-). Do you keep a mood/food/symptom diary?
You can get an NHS referral to a menopause clinic.
Many symptoms are due to a drop in oestrogen levels: this can cause the body to become dry, inside and out. Scalp, skin, vagina, deep in the ears, eyes. 4 me it was itchy insteps when I took off socks at night prior to stepping into the bath
and across the back of my scapulae. So using a good quality hand cream regularly has helped.
Olive oil into the itchy ears to ease any dryness down there as well as the above cream on the outer ear regions, difficult to scratch! Eye drops - ask your Phramcasist for something appropriate or buy over the counter. 'optrex' is a good product to try but must be used regularly.
Prior to each period I would feel breathless which went immediately the bleed began is there a cyclic aspect to this 4 U? As for aching muscles this can also be caused by a lack of oestrogen and should be eased with over the counter pain relief taken regularly. I have restless legs, several bananas a week cured that. Or 2 'nurofen' if it bothers me at night.
Dizzyness/nausea can be surges of adrenaline caused by hormonal ups and downs. I was told by NAPS to eat every 3 hours, even in the night and that advice certainly saved my Life. Even 20 years after I still keep to regular eating to stop that awful lurch when the body is hungry = intense sickness feelings.
Low mood can be eased by appropriate anti-depressant medication - some require that with HRT. Also any anxiety can be helped with an emergency drug "as necessary". Don't give up hope!
