Hi Sally4x, welcome to the forum.
Sorry to hear about your ongoing bladder pain. Your urinary symptoms and dryness certainly point to VA, so treatment for that could be helpful and I suggest you ask your GP for Vagifem. Using a vaginal moisturiser, such as one of the Yes products, would also be a good idea. If the pain continues after a couple of months, it might be worth seeing a pelvic health physiotherapist.
I have also been in treatment for embedded CUTI, although was with the Prof's team at 10 Harley St. All is well now, although I still have to take Hiprex for a while yet.
Best wishes,
JP x
