i had thrush a couple of days ago but it got really bad on a sunday when the chemists were closed. my friend told me to put some natural yoghurt down there because of the live bacteria but i didn't have any natural yoghurts but i did have some blue cheese i thought the bacteria would be the same and do the same thing. so i heated the cheese up a bit and spread it downthere. i have been doing this for a few days now but now my bits have turned a funny blue colour and the smell is awful. what should i do?
