Talk to your Practice Nurse about vaginal atrophy. I had urine infection symptoms intermittently for 5 years but my GP recognised a pattern. Treatment helps.
If you are asked to provide a urine sample make sure that it is sent to a Lab. for proper testing!
LIVE yoghurt for thrush Millykin - a lot eaten for 5 days and applied to ease the itchiness down there, keep 2 pots separate of course - 1 in the fridge 1 in the bathroom

- applied on an applicator high up the soothing cool yoghurt can ease symptoms - lay on a warm towel in the bed ;-).
