Numb Spot Above Left Kidney, Fear of Death

For two months I've had a numb spot on my back above my left kidney. It appeared suddenly one day and has not gone away. The sensation is similar to how it feels after your foot goes to sleep, and then right before it wakes up, when the feeling is coming back. It seems to get more intense, and cover a larger area, right after I take a dose of dewormer. Has anybody dealt with something like this?

I am two years into this cleansing process and feeling much, much better. It seems to me like I have gotten most of the little ones out of my system and there are just a few patches of them in me, places where big ones are lingering. Perhaps that is where the queens are buried...

If parasite colonies work like bee hives, then the whole colony should pack up and leave when the queen dies. So the question is, how to get rid of the mother loads, so the little ones will stop coming back. In my experience, it takes a huge dose to have any affect at all on the big ones.

The question seems to be whether I can survive a dose big enough to kill the big ones. I am hoping the fear of death that comes up in me when I am taking high doses, is me sensing the "fear" they are feeling, when they are dying off. But I do tend to have some pretty bad detox symptoms, including chest pain, joint pain, nausea and diahhrea.

Is there anyone who's successfully eradicated some big ones, and gotten rid of the mother loads with high doses?

I am especially concerned about the sensations I get in my head when I am taking high doses. It feels like there are bugs in my head, trying to work their way out, when I really get serious and start taking a dose every 2-3 hours, instead of just 3-4 times a day. If a big one dies in my head, will my body be able to clean up the debris quickly enough to prevent me from getting a brain infection?
