They look like flukes to me. I am sorry to sound disappointing but i have never heard anyone using any homeopathic remedy successfully against them.
What have you done before these came out?
You should stop wasting your time on doctors because their answers are ALWAYS the same, in every country on every continent.
Why dont you look up Mizmac here who has done a successful natural protocol here and he had flukes too. He has a blog with his protocol description. In his recent posts you will find the link.
Some had luck with pyrantel pamoate or reese's pinworm medicine as well.
You will need to be cleansing for months until they stop coming out and continue for months afterwards. Some recommended myrrh for flukes as well, a bit costly but some success, i have read. If you will not progress with naturals you might need to consider praziquantel but i would try naturals first. Of course you must remember never to eat undercooked seafood or fish anymore, a very common source for fluke eggs. In fact never eat any undercooked meat or fish, not even the smoked versions.
