ve read that one symptom of an overgrowth of Candida, which is found naturally in the gut,
mouth, and even skin, is skin rashes. I'm not sure how long these rashes last though. If you suspect having a Candida overgrowth, you might want to have your doctor take a stool sample. From what I have read, overgrowths of yeasts can lead to serious problems and has even been linked to some autoimmune diseases.
