I would suggest that it may be vaginal atrophy. If U experience full bladder symptoms, that's very similar to how I know that my sysptoms are niggling.
I wasn't particularly dry internally. My GP prescribed 'ovestin', an oestrogen replacement. As levels drop the body may become dry: inside and out; scalp, deep in the ears, eyes, nostrils, skin, vagina, vulva. As well as muscles may become lax = aches and pains.
Once you've had your scans I would ask for vaginal atrophy treatment. The idea is to insert into the vagina for 2-3 weeks every night then as necessary. Some find that they require it every night, others manage symptoms with insertion every 3rd and 5/6th nights. There are several moisturisers that can ease any dryness on the labia, i.e. sylc or yes.
Let us know how you get on.
