Blimey, you sound exactly like me. I am freezing right now!!
The heating is up, I have a fire lit and clothing , well I have loads of it on... mine too last for hours, then bang gone, then I get the f***** night sweats- aaarrg
Yes I am on HRT- it all stopped when I first started it, great, then all came back after 3 months, upped the dose, symptoms went away again and you guessed it, came back- so now I am trying a new combo and have slapped 2 patches on this morning!!!! Only supposed to put 1 on...
I had my oestrogen tested and came back 1164!, gp said mmmm rather high- tested me for everything under the sun= negative.
It has to be hormone related as I does go away for a while - but come back...... I am at a devil of a loss really.
