You could ask for Estriol Cream to apply externally, especially around the urethra. You never know, it might help. I didn't get on too well with Ovestin the last time I tried it as it stung, so that's why I asked for the other cream and it's been fine. You are correct that progesterone is not needed if you are only using local oestrogen.
I have only been in treatment with the Prof for 5 months, so I guess there is still a way to go yet. I was started on Cephalexin, which is what they seem to start most patients with, but I developed horrendous thrush a few days in. They halved the dose, and then at my 3 month check up switched me to nitrofurantoin (Macrobid), which I was told is less likely to bring on thrush. So far, so good. I have not had any real flare ups of symptoms since starting treatment, and no adverse reactions to the ABs apart from the candida on the first one. My original symptoms were repeated UTIs, which started at about the same time I became aware that I had VA.
Do you follow Jane Lewis (maryjane on here) on Instagram? She did a video interview with Dr Anderson not long ago. Might be worth a watch, as all Jane's videos are excellent. She has done several on UTI matters, and how NHS testing is not fit for purpose.
I am sure you will be in good hands with Dr Anderson. I know the thought of long term ABs is a bit scarey, but I'm glad I took the plunge. Will be interested to hear how you get on when your appointment comes round.
Best wishes,
