Hi and welcome MM Jbee
You are not alone with this. Urogenital atrophy can be truly ghastly and sadly not recognised by many doctors - so appropriate treatment is not always given.
To keep things under control these are my strategies:
Drink lots of water.
Avoid Caffiene, fruit juices and alcohol.
Take showers not baths and never use anything scented to wash your ‘lady bits'.
I use Vagifem 2-3 times a week.
I use vaginal moisturiser every day - SYLK or the YES products are the best - these moisturisers must not be used at the same time as local oestrogen treatments as it may block absorbtion, so if you use the oestrogen at night, use the moisturisers in the morning.
Clean really well after opening your bowels.
When the urethra starts to burn, I then have half a teaspoon of bicarbonate of soda in a glass of water 2-3 times a day for 2-4 days.
Ovestin did make my urethra burn - it's probably the fillers in the cream that does this so I prefer Vagifem.
Try taking a Nytol at night for a few nights - the over the counter one with an antihistamine - as this can calm the bladder reducing the need to pee so often. Nytol will also give you a better nights sleep and I expect you are really needing this right now.
I am sure you cannot see your life getting back to normal right now - I've been there so I know - things will get better but it will involve some simple lifestyle changes.
Keep us posted. DG x
