That is rubbish, and you have every right to be angry about your time and money being wasted, your intelligence being insulted and your condition not being treated adequately.
I'm frustrated with your gynaecologist too just reading that!
I wouldn't bother waiting 6 months for a follow up there, you need to see an actual menopause specialist.
Does Canada have a menopause society or equivalent that can provide a list of recommended doctors?
This is something that is worth paying out of pocket for, just like many women sadly have to do in the UK too.
Also imvexxy is just estradiol - can't you get a generic? There is one in the UK called Gina that you can buy over the counter.
I would also seriously consider systemic estrogen, you can always use topical as well but then you wouldn't be depending solely on something that you can only get a pitiful supply of and someone quibbling over whether you can use it once or twice a WEEK!
