I have just come through a flare up of V.A and the symptoms were exactly like having a uti and running to the toilet all the time to pass a little bit of wee.
Reloading with vagifem has helped massively. I have had the same issues with vagifem pessaries coming out undissolved and then someone on here (sorry can’t remember who, but thank you!) suggested dabbing the pessary and applicator in a little of water-based Yes Wb before insertion and it worked like a charm. I think it must have helped with the dryness and also kick-started the process of dissolving the vagifem. I think the pessaries coming out undissolved fuelled the flare up, and also I probably because I stopped using my patches for a week or so to see how things went without them and I think that upset the applecart too.
Hope you feel better soon x
