It would be better to know which one you are dealing with, and not be guessing- especially because of it getting worse instead of better with what you have already been trying.
One thing that I have appreciated about the ND, is that he has also included different types of tests to go with what he has done with the biofeedback. People get a mad-on at how much they feel they have been let down by medical Dr's- that's alot of who the CZ community is made up of..but I'm seeing things in a different light too. Different types of Biofeedback testing, has been very accurate with knowing what I have had to address. But, I have also been one of the few fortunate ones to have been led to a good ND right off the bat too. It's far more than just the parasites that has been involved with me, but I never would have known that on my own. It's definetly toxins, and bacterias, and viruses that are also involved. But, much more too- including food allergens I didn't know I had.
One thing that has always been a concern to me with people trying to do all this stuff on their own too, is how focused killing stuff becomes, it's like an obsession that takes over.. and yet an important thing that is over-looked is- why is the body/immune system weak/deficient to begin with, and what is needed for rebuilding too? What other things are going on besides the parasites? The longer a person has been sick, the more nutrional deficiencies, and imbalances there will be too. Sick elimination organs that aren't addressed at the same time, and kept open (with the killing being the main focus), is a train wreck sure to happen.
Search for answers for yourself, and for what is going on with you specifically. What works for one, may not be at all what is going on with you. That's the danger, I think, of the different CZ "protocals", that don't look at the much bigger picture of what all else can/will be involved too.
Someone said it accurately too-- "remember that it's a marathon, and not a sprint".
Like my ND told me from day one- "there's alot of layers to peeling this onion". I don't think he even knew how accurate that statement was going to be with me. I have been one of his more challenging patients. His wife, also his receptionist, made the comment to him that she didn't think it looked very good that people weren't better within 6 months to a year, using me as an example. He told her that most people think they can just do one thing, like kill parasites, or kill candida, and not address the other things that also go with them, and then wonder why it didn't work.
After having a long-time CZer, and friend, recently discover that she has definite heart damage that has been going on for some time now, I think it is important to find out what more may be going on too. It is not shameful, as some people feel on CZ, to also include medical things like a pap smear.
