I have pudendal issues also . I am really sorry but I don't no how to direct you.
Are you from the UK ?
As far as I am aware UK , you can stay on HRT for ever re the latest guidelines , so long as you are aware of the risk/ benefits. By the sounds of it coming off the HRT has sparked it all off again?
My VA/pudendal / vulvodynia started 4 years ago age 46 , now 50.
I am not cured , but managed it has taken a lot of trial and error and I will be on HRT for the rest of my life.
I have seen the very best the UK has to offer re PN/ vulvodynia/ VA, bottom line for ME is the bladder/VA issues causes atrophy which tightens around the PN nerve and causes irritation , and I am sure you are aware the vulva is one mass of tiny pudendal nerve endings that once irritated are hard to calm down , as they get over sensitised and for me there is no magic bullet.
I use 1.5mg of sandrena, vagifem should be daily but I use it every other as it can irritate in itself , estriol rubbed into my old episiotomy scars also.
I also use twice a day a blob of multigyn act gel with YES oilbased mixed together and massage into the vestibule, I have tried many other lotions and potions and this is the best at the moment for me.
Some ladies also take drugs like amitriptyline to calm down the nerve pathways ( I don't ) , some ladies take an antihistamine twice a day to calm down the mast cell receptors in the bladder , for some this helps a lot.
Sitting too much is bad if this effects you. I can now wear pants and loose fitting jeans again , so that is progress.
I eat very healthy ( I have a nutritionist) my immune system has been pretty poor , but I am seeing good improvements , I take a very good probiotics/ vitamins/ and digestive enzymes.
Some ladies see a women's health physio , these need to be researched as a bad physio is worse than no physio.
You may also have an infection ( regardless of a negative result) a bio-film infection that attaches itself to the bladder wall , and is very hard to detect , and only a tiny handful of experts worldwide can deal with this, and treatment is gruelling.
The pudendal nerve also innervates the urethra and can become a chicken and egg situation.
If you have any other questions please ask , as VA/ PN/ V are miserable conditions to have and life changing as they stop/ change so much of what I can do.
