I feel your frustration!!! I myself, using deductive reasoning have also deduced that these small blisters that I have had mostly on my face, but also on fingers and toes (for about a year or more now) are probably from candida. Yeah, I notice they come back the more sugar I eat and I didn't used to be like this. I have had digestive problems for a  couple of years, getting worse, and after learning about candida, leaky gut, etc. I am pretty sure that I have candida overgrowth in my gut. I have tried different probiotics, but I couldn't take the severe pain I got in my gut from taking them! (I don't know why, even Activia makes me feel like someone is stabbing me in the abdoment!) I am going to buy some Oreganol P73 and start taking it, because several years ago, I remember hearing on the radio a man that invented? this product was talking to people calling in, and one guy described blisters like ours and he told him he had an internal fungus toxifying his whole body, etc. (i can't remember if he said 'candida', but)  this stuff is supposed to help with many, many conditions-look it up-it's not cheap, but I am at my witts end, you know you can't talk to regular doctors about this kind of thing, alot are ignorant about alot of these types of things. I told a doctor I feared I had a malabsorption problem, and she shook her head telling me people don't gain weight, but lose weight with that-I told her sometimes you can gain weight-she wouldn't listen...

I hope this helps. I read about people having to be on raw vegetables, no sugar, yeast, mushrooms for like six months, and such, and I thought, there is no way I could do that!!!! I hope this helps  yourself and others God Bless:)
