How sad, it's so so horrible when they cry. Both my RB boys suffered with this; Eric had a bladder stone and Larry was diabetic with an extremely thickened bladder and spondylosis of his lower spine, which contributed to the pain when peeing and pooing.
I hope and pray you can find something for her that helps long term


It really is heartbreaking when all you can do is try and soothe them
Hopefully the surgery will ease her discomfort somewhat.
