Hi red,
I am not certain but it sound as if they could be liver flukes. Most folks when describing liver flukes post that they look like rolled up tomato skins. That is what I saw and called it before I read about others seeing the same.
You can go to images at the top of the page and click on parasites then look for flukes/liver flukes and/or a-forum then look for ask humaworm and again flukes or liver flukes...
