I use Vagifem and Ovestin, and moisturiser every day without any problems from my surgery. Side effects of the treatments are annoying if it stops you from increasing the dose but it's perfectly acceptable to use more VA treatment if necessary.
I also agree about winter clothing making matters worse with symptoms, I just have to wear tracksuit trousers and it will give me a flare up, but just whilst I am wearing them, I mainly wear long skirts when indoors.
