AAAHHHHH. ..........
Sounds like another GP who needs to stick his/her head down the loo and flush. Several times
Lots of info about 'bladder issues' and vaginal atrophy on this site. Browse round. U don't have to suffer.
Who has offered the regime you have been using?
GPs usually prescribe either: "vagifem" which is delivered by a think a small tablet into the vagina to stick on the 'wall' to release slowly; or 'ovestin' which I use delivered into the vagina in a measured dose in an applicator. The advantage with that is that 1 can use a smear on the vulval area too. Some find that using a moistorisor such as 'sylc' or 'yes' can help too.
There is a product available OTC from Boots called I think, 'gina'.
There is a book called 'me and my menopausal vagina' which is worth a read. Written by a Forum Member and her daughter a few years ago ...... to educate women who can they pass on the book to their GPs . I did, several times.
Up the estriol to every night for as long as is necessary, 2-3 weeks at the very least. Ditch the Replens and use KY Jelly if suitable or 1 of the mositorisors that can be useful.
When I get the need2P I swallow two Nurofen 3 times a day to ease the nip as the spincter shuts off the urine flow. It relaxes those muscles.
Let us know how you get on. It's 1 subject that we know a lot about.
