I agree that chelation is probably the only natural treatment out there. IV chelation with EDTA would probably be used and followed with vitamin replacement through IV as well. I HIGHLY suggest a Medical Dr only, who works a lot with this type of treatment. A complete physical and bloodwork should be done beforehand.....including labs to show kidney health.
Now there's a good one! Anyone who knows the answer to this one deserves an award. I googled it, basically calcification would be treated by surgery or some form of chelation, in other words, taking something like magnesium that leaches calcium out of the body, but in this case, because of where it is, who knows? It's an avenue to pursue, perhaps. Is it causing any symptoms? Seems to be something from birth, so probably harder to leach out than calcification elsewhere, and since calcium is hard, when it occurs from arthritis or in the teeth, the treatment is usually surgical. Good question, sorry no answer here.
