It is hard to tell what is really affecting you. Fungus can be one cause but other things such as bacterias, immune deficiency also can. Bacterial overgrowth in the gut also respond to a low carbohydrate diet. Anyway, until more complicate be the symptoms and the diagnostic, more simple is the treatment. A perfect whole food low carbohydrate diet, supplements to detox and to combat candida and bacterias, immune booster, light exercises, and some relaxing technic to lower stress. There is no more that I know. It is the main point of Holistic medicine.
