The ones in the brain (or anywhere) need to be cleaned up...by using L-cysteine according to Hilda Clark. That is where I found out about it, after one does the COQ-10 cleaning then go after them with that. I do remember reading somewhere on the web about Tapeworms escaping the intestines and then traveling up the spine to the brain and then living in the brain. I know I had (have) a nest at the base of my spine at the neck area, because once I was seated in my recliner and I felt something poking out of me at that area. Freaked me out! Like it was saying "I am here...." They do wiggle and move when I feed them Sugar in my gut and they seem to constrict...yech yech!! And I can feel them slide against my brain at times. The ones I have in the head seem to shrink when I take the Valbazen and so I do not feel them later on in the treatment. But I still feel them when I take the L-cysteine when it hits them at the head. It feels like a pinch or a bite in my head.I believe the L-cycsteine also weakens them also. I do not have any bumps because I did not let them get that big in my head. I have also felt them in my right thigh, chest area, my right foot, right knee and anal area. I do know where most of them are. The best thing to do is to just keep killing whether you feel them or not. I just have been dealing with this so long I have been sensitized to feel them.
