TMI about vaginal issues.
I had thrush constantly for about 12 months and in the end I went to a naturopath who helped adjust the flora in my gut... It sort of worked but it didn't cure it completely. I also cut out sugar and carbs, took the edge off but it was still meh...
Then one day I found a pamphlet in a chemist about the vagina and I got talking to one of the ladies there and she suggested that perhaps it was dermatitis and recommended washing in pintarsol (obviously you don't wash up there with it but around...) I also stopped using disposable pads and tampons and I don't think I have had a "thrush" attack since. Just some food for thought :) I'd get a swab done tho, yours sounds a lot worse than mine was and it would be good to rule everything out.
