Hi robotwars and jasmine,
If you do try 'Yes' vaginal moisturiser, make sure it's the water-based one - it's a gel and also pH balanced so should help prevent thrush, as well as being very soothing.
Also plain live bio yoghurt is very calming on itchy/sore bits, whether it's to treat thrush or not!
Hope this helps and please let us know how you get on!
