Everyone's responses are incredibly polite. I'm sorry but the consultant sounds like a real bitch to me! She may have some sound reasoning for wanting to clear your system and run fresh tests. Who knows? No one knows because she obviously did a terrible job communicating with you! That is frustrating, but don't despair. I've found (in other issues in the past) that some doctors either don't understand me or I don't understand them. Whatever the case, the communication is broken and I end up feeling belittled and frustrated and that I'm wasting my time and I'll die before I find help.
As I said, there may be sound reasoning behind the consultant's course of action for you, but this consultant is not going to work for you. Personally, I would follow her recommendations while you are seeking another consult. That way, if the next consult suggests the same thing but explains it better, you'll not lose any time waiting for the hrt to clear your system.
I'm so sorry you're going through this. I have a great gp but kind of got caught up with a similar gynecologist before I got too frustrated it all. My gynecologist actually told me I needed to decide who would handle all my care (thyroid, perimenopause, annual exams, etc) her or my gp, that she wouldn't treat only my gyne issues. My gp has handled the rest of my body for years, doesn't belittle me, and I can get an appointment when I need it or a personal email response, and I don't have to chase him down for lab and scan results. You can imagine it was not a hard decision to not go back to her.
Find a good doctor. There are some out there.
