Thanks for the response. I just did some reading on the strongyloids and zoonotic filaria you mention and I don't have the symptoms that are described. When my symptoms first presented, I had a very itchy anus and white threadlike things in evening/am around anal area. I feel "movement" of the worms in that area. That is why I settled on pinworm as my self-diagnosis even though doctor's haven't been able to confirm. My family practice Doctor saw what he said were "helminths" over 6 months agao when looking through the microscope but they did not find any eggs. I find "white things" in my underwear/around anus most mornings although the itching has lessened (perhaps I am just used to it). I appreciate the suggestions about ways to get the fat required.
