It took me longer than a year or so to get right but I had a prolapse too and had left it a long while due to ignorance, plus the dryness and burning came on very suddenly with no warning.
Have you any other menopause symptoms Jules? Some women find going on full HRT very beneficial to their wellbeing and feel like a new woman.
The GP I first saw was a woman and when I asked what was wrong, I thought it was an infection or worse like cancer, she said had I never heard the saying "dried up old woman". I've never gone to her again. Not much sympathy with doctors, old age and menopause are not an illness so thats it. I suppose they have too much serious illness nowadays to deal with as the NHS is in a terrible mess.
If you can afford it maybe go private.
