Hi Kirsti, and a warm welcome to the forum.
I am so sorry to hear about your mum. This could well have an effect on how you are feeling now, as stress does have an impact on VA.
Vagirux is the same as Vagifem as far as I know, so ought not to make a difference. What is your usual dose? Many women are underdosed at only two a week, you could try using it every day for as long as it takes, then cautiously reduce the dose. The addition of Ovestin on the labia might also help.
Tension in the pelvic floor also impacts how we feel in the "undercarriage", and this includes soreness and the urge to pee (the bulboglossobius muscle can cause that). Assessment by a women's health physiotherapist would help you know if this is part of the problem, and you can be taught techniques to help.
Hope this helps.
