Yes Vagifem would help over time and many women need systemic and local oestrogen together. I didn't get on with Balance active - do try MultyGyn Actigel ( buy online). Nine of these treatment will work straight a at - it takes at least a week to work it's magic and restore the balance. I use a good dollop of Multi Gyn 2-3 times a day for 3-5 days when I feel the flora balance is off (itchy, sore, strange smell, watery discharge etc). Nothing his going to work instantly either - it will take some time for things to settle.
I do think you need to get a urine sample to the GP for testing though, just in case. Please do that today.
Have you been drinking a glass of water with a teaspoon of bicarbonate of soda 2-3 times a day and then lots of water in between? In this hot weather we are far more prone to infection around the vagina, bladder and urethra.
No tight clothing , feet up when possibly and let the air to your ‘lady bits'
