This isn't a crazy person disease.
This is a fungal infection that attracts mites and other type insects.
Not just one insect.
insects can lay eggs on or in the skin.
insects do carry bacteria / fungus.
That much about bug Science in general is known.
it's very rare when a dr will do a skin scrap.
Then even when a scraping is done, it damages the specimen.
Many people that have had scraping done, either come back with negative results and or agro bacterium with some unknown DNA possible from an insect. But it's so degraded they can't always determine what it is or isn't.
Any info u will read about bird mites is OUT DATED AS ARE THE DOCTORS DOING THE TESTING.
