The same way people have labial herpes and never get cured others like us have resilient parasites like fungal forms in the skin, scalp, face, behind years that are hard to fight.
You must go to a good laboratory, get flakes of your SD skin and ask them to cultivate the parasites you have.
They will report fungal resistant forms on you.
Look at Dr. Simoncini an Italian doctor and you will understand how hard fungal forms are to kill.
Stop believing that this an internal organ problem or psico problem or anything transcendental. It's just fungal parasites you have.
Then do like me and others suffers use Baking soda and coconut oil to control the parasite population.
