candida - toes and tongue??

Hi. I've been treated for parasites and candida in my small intestine; both the parasites and candida were found in a stool sample. The candida and parasites were not on my last stool sample, but there is still candida on my tongue and toe nails. It's getting better, but very slowly. Does this mean that I still have the infection in my small intestine? Or is it possible to have a local infection on my tongue and toes but not in my small intestine?
Thanks!
