I had this crawling. itchy skin I used Aquaphor to calm it down, until I figured out the cause, but it was high doees of vitamin C that stopped the crazy itching
Later we found hidden black mold in our house, and the stinging, crawling, itchy skin was the first symptoms I had! I saw ten doctors all of them were clueless
of what ws causing the issue. . Later I was treated for candida too, but now I really realize that it was black mold that triggered the skin issue
