This may sound freaky but when using yoghurt for thrush I put a bit in a sterile 10ml syringe and gently, slowlysquirt it up there. Make sure there isnt air in it and dont put the syringe right up there or anything.Put it just inside because it does help to actully get some inside where the infection is rather than just outside where the itching is. You just use natural or greek style yoghurt and after wash the syringe and put it in a little container with some miltons sterilising solution till next time..... It is kind of cold!!! As Alan said, it only helps if it is thrush, not if its hormones causing the itching.
