Absoulutely! I may not know the answer to the rest of your question, but I can certainly tell you about intravenous chelation therapy. There is a forum around here somewhere, but there are also lots of websites that describe this wonderful treatment.
I.V. chelation, as opposed to oral chelation which IMHO is not nearly as effective, is primarily used to remove heavy metals from the body. It also dissolves plaque build-up in the arteries and has saved many folks (peeps :-} ) from having to go under the knife for bypass surgery. This I can testify from having personally met many such individuals while undergoing chelation myself.
I took a series of 30something chelation treatments to have a mercury build up removed from my system.
The list of symptoms alleviated or totally resolved by I.V. chelation is numerous.
