What a relief to get a good and more specific diagnosis. Good for you. You now have a target.
MMS did nothing for my candida or fungus outbreak. I won't say absolutely nothing, because I sure had some heavy Herxheimer reactions at about 6 drops in. I was on the early old fashioned protocol, not the every few hours one. For nine months.
Anyway, your specialist is quite right about controlling the candida. (Oh gosh. Here he goes again.) I know. I know. Y'all are already tired of hearing this. Candida is part of everyone's flora. The best you can do is control it. pH is the key. I always believe that the body will manage you pH quite well, but sometimes it is overwhelmed by your own manipulation. Of all the fungi, Candida is one that is bimorphic. It naturally exists as a bud in the yeast state. When your pH environment becomes more alkaline, it thrives and switches to the fungus state. Given long enough, it can become systemic. This is why it is necessary to avoid things like antacids or anything you might do to raise your pH. This is also why I don't like the MMS protocol that calls for more frequent use during the day, because it is alkaline. Once or twice is plenty, if you use enough.
Acids will kill the candida. Probiotics kill it by producing lactic acid as part of its fermenting process. My favorite is undecylenic acid

If it is systemic, I feel sorry for you already. One thing that is important to remember is that just like antibiotics, anti-fungals can create even more aggressive fungi that adapts over a period of use. Rotate them. Use one for 2 weeks, then switch to another.
Good luck.
