How badly do you want this gone? Pioneer and WannaSeeWorms are telling you correctly: Get Barefoot's Dewormer - two tablespoons a day morning and evening for two weeks and liver flush. The parasites will go; it will take awhile but they will go. Don't keep wasting your money on Drs' opinions. In the end, if you feel that you have them and you have a problem, then, that is all that matters. Yes, it is scarey doing this at first. But it gets easier and easier. Try it for three months, then, look and see where you are: If you are feeling better, then keep going. If not, try something else. I believe, as Pioneer, that you will see improvements in three months (please notice that I didn't say 'cured' in three months). You have already probably spent more chasing tests and test results around. Hope this helps.
