I think the likelihood of what is happening is that your are killing something in the body (candida or parasites) that are releasing toxins which are then detoxed via the skin. This is why it has gotten worse. In the long term, it should completely heal, but you might have some flare ups as the flora in your gut rebalances itself.
Vitamin C is very good for the skin and highly recommend it! Acupuncture can reset the body and bring balance.
Also a mineral spring bath can completely heal your skin woes because of the sulfur.
Dr. Mcoomb’s stated that anyone with skin problems needs more HCL because your body isn’t producing enough…I would try this out as well.
