Doctors do not do parasites, because smart humans do not get parasites. Mentioning parasites to them and they will give you a quick referral to the cookoo house. Just tell them about your symptoms. they understand symptoms. Or just get busy saving yourself.
Unless you are a cat, cow, horse or dog, you cannot get treated for parasites. So folks get ivermectin and fenbendozole horsepaste from net or animal feed store.
