Scattered parasites

At first I treated my parasites, probably roundworms, with herbs. They scattered and I felt it happen. I then followed ICU's protocols many times and feel that most parasites are gone, but for the ones remaining in the legs. They have been there now for two years and are getting quite large. I even have leg swelling from lymph fluid problems now. It frightens me to think that none of these prescription meds killed them. Is there anything left to do? I've tried it all, laser, drugs, zapper, etc. Please help. Will they eventually die of old age? There isn't a doctor in America who would believe this story.
