This is correct. I first learned that I had a problem when I had terrible’UTI’ pain. The urology clinic sent me to a uro-gynecologist. This was years ago and I still see her. She diagnosed me with pelvic floor collapse and put me on the estrogen cream. She also sent me to pelvic floor PT. This worked and I keep it up. She and the PT explained that when the vaginal walls thin out, so do the tissues of the urinary track. Thus, pain as with a UTI.
