After I self-diagnosed, she agreed to test a stool sample for parasites, bacteria, etc. and said that she had never seen such high yeast levels in a stool sample. So she believed me and gave me a packet of info about the diet and supplements, and said to do more research online.
That was back in early May and I'm doing much better now. I'm going back for a follow-up appointment next Monday and hope she'll do another stool sample test to check for yeast levels. I think I lucked out that she is aware of Candida and believed me!
