I have had the same thing for years. Like you, I think it is strongoloids.
In reading many medical papers I have concluded that it is nearly impossible to ride yourself of the infection.
I know everyone is into these herbal remedies but I just think they make the seller rich and you sicker.
I have found that increasing the calcium, magnesium, vitamin D supplements has helped a lot.
Clark believed that the strongoloids could only be stopped by blocking them with calcium. I don't eat dairy because all of it is full of parasites so I just do the supplements.
I do 1000 to 3000 mg of calcium a day. 10,000 Vit D. Magnesium 1,000 to 1800 mg a day.
Too much mag can give you heart failure, calcium is the antidote. I take as much MSM as I can tolerate. Alpha lipoic acid, vit C, soy free omega-3, etc.
Wish I could help you but I can't. no one seems to know the answer to this one.
One more thing. I sleep with an ice bag on my liver to reduce the swelling.
