Menopause is probably one of the factors that are causing this, or making it worse. So you can look forward to an improvement, I hope, when you are through the menopause.
Talk to a nurse who specialises in urine incontinence. She will know what can and should be done.
Have you tried pelvic floor exercises? They should help bladder control, you know.
Buy a she-wee and place a bucket in a strategic position near your bed for weeing at night. This will give your hip a better chance of recovering soon.
And the fact that you know the inconvenience of getting out of bed ,to the bathroom, and back has been ruled out, you may actually find you don't need to wee so much.
I know that sounds daft, but the more you think you might need to wee, the more you will need to.
I assume you have tried drinking the bulk of your fluids during the forenoon and afternoon, and setting a cut-off time in the evening, as we did with bed-wetting bairns.
