as to the question - "Does anyone have any idea how chelation caused more health issues for me?"
This is just my opinion, so take this for what it's worth. I am a firm believer in the concept of chelation, but also firmly believe chelation has not yet been rendered to an exact science. It seems more like a potential mine field for which there is ample good reason for one to traverse but from one person to the next, there is also ample good reason for one to traverse carefully and cautiosly.
Question - before you started your chelation method, had you already removed (to the best of your knowledge) the kinds of sources inside your body that generally act as permaent reservoirs of mercury?; for instance, had all Amalgam
fillings and root-canaled teeth been removed? Assuming the answer is yes, this at least leaves you in a better (*) position from which to continue traversing the chelation mine field.
* this is a matter for debate given that there are chelation methods out there said to work well for people who have not removed all such sources/reservoirs. Regardless, it is generally accepted that the prospects for successful chelation are improved if one first rids (such as through dental cleanup) any and all sources/reservoirs of mercury. The gist of this logic holds as this - trying to chelate mercury out of your blood, bones, brain and other body parts becomes somewhat the vicious circle. Lets say you take try a chelation method, and it successfully removes the mercury from your blood. Well, that reservoir in your mouth called a filling is still putting out vapor 24/7, so it pumps some more mercury into your blood. If you first remove the reservoir, then it stands to reason that whatever method one uses to chelate will have better chance to succeed long term.
In lay terms, which is mostly how I understand this topic, an Amalgam
filling inside a tooth is a specimen form IE> what is generally thought of as a permanent source/reservoir, although in reality, few things in this world are truly permanent. This mercury gets put into a tooth in solid form, generally mixed with other heavy metals such as silver and nickel, but the point here is the form of mercury. From the moment this form is put into the tooth, it is outgassing, so to speak, or in other words, it's putting off mercury vapor..... a different form of mercury but this form is just as hazardous to human health, if not more hazardous, than the sollid form. The vapor form can probably be thought of as one of the primary by-products of solid-form IE mercury filling. This vapor can then leach into other places in the body beyond the location of the tooth where it was installed in it's solid form. A likely first place for it to leach into is the blood stream, which for sake of this argument is akin to the mercury now having a vast super highway upon which to travel to other destinations of the body. Over time, from many months to years, mercury that's been allowed access to the body's bloodstream has been found to eventually get off the highway at some unpredictable exit in order to find a more permanent home, such as the liver, or heart, or lungs, or brain, or bones and in some cases into the very fiber and cellular composition that makes up a body.
Pretty much any and all chelation methods are hoping to provide the body with a substance that is known to be an attractor to mercury...... like the veritable lady of the night working a street corner "hey there big boy, whadya say you, me, get together and bind for a while?". The hopes are, a chelating method will provide subtances to attract mercury, then bind the mercury and keep it bound (handcuffs, so to speak) until it has been expelled from the body, such as through the body's eliminative organs that dumpt stuff into a toilet.... problem is, this doesn't really eliminate it mercury in it's entirety, it simply removes it from one body (your human body) and dumps the problem onto some other body, such as your municipal water/waste treatment facility. They too are pretty good at ignoring the issues of mercury.
Mercury that is in the bloodstream is generally considered easier for such a chelating method/substance to find, attract and bind. For one reason, this is because the mercury is already in a condition of generally and freely floating around in the blood.... walking the streets, so to speak. By the time mercury has seeped into the actual organs and structures of the body, it then becomes a lot more difficult to remove.... kinda like criminals and politicians going underground. In these places it's not walking the streets anymore, but is instead
keeping a low profile tightly locked up inside some place, the liver, the lungs, the cells. In these cases, before it can be attracted by a chelating substance, it must be first stirred up - like a police raid on a big secret underground meeting that sends the particpants scattering into the night like a flock of cockroaches.... okay, work with me on this, pretend we still live in a world where the police generally uphold their oaths of public office and actively seek to root out underground politician criminals ;) Once stirred up and out of it's happy home inside your liver, for instance, this mercury is again much more eligible to be attracted and bound to a chelating substance. However, some substances do not bind as tightly as others..... it's a complex situation. Sometimes, while bound mercury is being escorted from the body and to a toilet, some other substance, like the NSA
or MI6 or wag-the-dog presidentail decree, may happen by. These kinds of substances and agents may have more of an affinity for the mercury (IE> they may have a stronger attraction to the mercury than does your chelating method). This may cause
your binding agent (like the IV method you used) to let go of the mercury, which sort of put's it back in the position to freely roam your body to again search out a new, dark, damp and deeper recess of the body to continue it's malevolent agenda.... this is generally referred to as "redistribution".
This is pretty much the extent of my lay understanding of the chelation dilemma. In summary, sources/resevoirs like solid mercury fillings, act to perpetually put off other forms of mercury, like vapor, which in turn are then free to travel the body and cause all kinds of problems. Chelation is intended to provide a subtance or substances that attempt to act in concert with each other to attract, bind and expel mercury from the human body. There are enough variables involved with this saga, including bio-diversity from one person to the next, that the removal of mercury from the body does not always progress on a nice, neat and problem-free basis.
