I've contacted Dr. Chieu through email and he has identified them as intestinal flukes. He has been a blessing in my life. He has sent me medicine and has been amazing in this issue. He is a nice guy and seems to really care about the patient not so much the money. I recommend anyone with this problem contact him. I don't remember his email address right off hand but can post it shortly. Also you can search him on curezone.com by entering vo duc chieu in the search box.
