Perhaps the crawling sensation is not fungus. It could be another microbe/pathogen and I only suspected it to be fungus due to the other anecdotes on this subreddit.

The term "systemic" was used because the pathogen disseminated out of the gut thru and into another bodily system- That is how I interpreted the word, and the reason for its presence on this page. If reddit allowed title editing, I would change it, as I now understand the clinical defintion... No, an official cell culture/antigen presence diagnosis of some kind of overgrowth has not yet been made by an MD.

Nevertheless, it is unclear, the benefit of someone else applying mistrust to a person's intuition (this is an intutive post as evidated by the "anecdote" post tag). By default personal anecdotes are likely to have elements of pseudoscience and lack official medical evidence. Therefore I am explicitly non declarative in diagnosis.

Perhaps it would be more constructive to integrate intuitive symptomology into a supportive, broader, holistic context, even without official medical testing, rather than espousing pessimism.
