Hi Fletch6823
from me too.
Sorry to hear about your problems and how you are feeling.
re HRT - if you have taken it before and haven't been off it for that long then provided you do not have any risk factors ( for cardiovascular disease, stroke etc) if you are still experiencing flushes and sweats then your GP ( or failing that after referral to a menopause clinic) should be able to restart you on a low dose oestrogen. The beauty of it as I expect you know, is that you don't need progesterone which is the stumbling block for many women on HRT due to the side effects and bleeding.
If your GP is useless then can you see another one in the same practice? There is no longer any age limit for hRT provided any risks are discussed with your doctor. If you would like links to current guidelines then let us know - there is also the British Menopause Society which has up to date statements.
Please reconsider and you can hopefully restart and try an oestrogen patch - starting low dose ans building up to medium dose if necessary ( 50 mcg).
re your weight gain - have you had blood tests to check thyroid function - and if so ask for a reading of your results? Many women suffer from underactive or sub-optimal thyroid at this stage of life which can cuase fatigue, muscle aches and pains and weight gain ( as well as feeling cold) and lead them to get "dustbin diagnoses" ( I remember someone calling them that on here recently!) of CFS or fibromyalgia when in fact their syndromes are caused by hormonal imbalances.
I am mid 60's and still on HRT (for past 11 + years) as well as testosterone.
Good luck with finding a suitable doc and treatment and let us know how you get on.
