Please help with identification.

I send these off to lab for identification and the results are non-parasite. I assume the med tech at the lab had not seen these before. Does anyone have scientific literature with photos or links that can identify it? I have done research for weeks and the closest I can find is live flukes, but it would have to be different stages. I can't find photos that match, biology sketches that seem close to liver flukes.










Multiple Ova/ parasite stool samples were negative. I traveled to Korea and Japan 20 yrs ago, but the CDC said flukes have been found in the US. I'm in the medical field and I would like to have evidence and know exactly what it is, probably everyone does. I dislike treating for everything based on symptoms alone because in the past I end up with one random side effect only 1 in 100 experience.

In case someone has had the same issue and knows how to cure it.

Symptoms:
occasional diarrhea
fatigue
food sensitivities
anal itching (not hemorrhoids, yeast or irritation from diarrhea)
brain fog

I have seen physicians, a natural minded MD and a DC in functional medicine. I have taken, Zymex and chanterelle mushrooms for months, Albendazole 2x, Prazitol 2x, and pinworm medication multiple doses and tolerated all of those well. I tool another antiparasitic but can't find the the name. The parasites showed up after treating the last time with albendazole. The symptoms improved but returned within a 1-2 wks after discontinuing. I'm hypersensitive and react to most rx medication and many natural remedies. I've tried parasitol which contains black-walnut, olive, Wormwood , garlic etc... in it and it they make me feel too sick and unable function,(cannot do that for weeks or months). I also tried take to charcoal with it for die off also treated household so reduce reinfection.

Thank you in advance for your assistance!
