Hi, I am new to to this site and just read your post.....I was told to look up the yeast free thing,,,,I am in such pain all the time and...OH, long story,,,,Anyway, I don't ever get a yeast infection, ever.....So what would yeast have to do with me being in pain?
i had this problem last month and went to a nutrionalist at a health food store and she recommended acidophilus on a daily basis. i also started eating kim chi, which i had to get used to (its a spicy korean fermented cabbage dish) but it contains the good bacteria in it. i would think if you do things in moderation (anything not on your list) you should be ok, but our bodies ph levels are constantly changing and everythin effects that. same w/ our bacteria levels. maybe go to your local health food store and ask some questions. they usually have a nutritionalist on site.
You can also buy vitamins on the internet that should give you what you are missing. I don't get YI but I commonly get BV so I kinda understand what you are going through. Do a search and maybe that will help as far as the diet I am not sure.
