Maybe the pain you are feeling is liver Flukes burrowing into your liver?
What's your diet like?
Also, Have you been checked for Ammonia?
die they release ammonia.
This would cause a lot of issues, Nausea, pains, insomnia etc.
Use L-Ornithine for this.
I would recommend Ornithine for every cleanse/flush because it helps remove ammonia from the body.
I was getting really bad head pain (Bruise scalp, hurt when I pushed down on it).
Took ornithine and the pain subsided. I know if I don't take it for a couple days and eat seafood my head hurts really bad until I take it.
