I had a very difficult skin yeast infection earlier this year that I had a lot of trouble getting rid of, and your post sounds so much like you are going through the same type of struggles I went through. Not even two rounds of Difulcan and six months of Nystatin treatment worked to totally get rid of it, although they did help. What really worked to kick the overgrowth of yeast out of my body was Humaworm. I can't speak more highly of it. After I took Humaworm in April, I've been totally yeast and fungus free ever since, much to my delight. Although Humaworm is mainly known as a an anti parasite remedy, it also has a lot of very effective antifungals in it which, in combination, really give difficult yeast and fungus a knock out punch. Anyone who has a serious fungal or yeast infection that they are having a really tough time getting rid of should seriously consider trying it.
Best of luck in your continued recovery, and please let us know how you are doing.
