I think you will find most MD's in general do not deal with heavy metals unless the person has blood tests that show toxicity - which means the person has had a huge dose all at once. So for the rest of us with subclinical toxicity, we have to find help from alteranative or integrative medical practitioners such as Naturopathic Physicians.
Yes, the protocol of B12 injections and liver makes sense for neurological symptoms because Lyme eats away at the myelin sheath and this cannot be repaired without B12. The liver also must be supported when there has been neurotoxicity because the liver is a key detox pathway for these neurotoxins (ammonia ~ from Lyme/coinfections, aldehydes ~ from yeast/probably other infections, etc.). What form of B12 are they injecting - is it hydroxy, methyl, or cyano B12? Just curious...I would think they'd want to avoid methyl B12 because methyl mercury is the most difficult form of mercury to excrete and tends to gravitate to the brain....or so I've been told...
I know of one integrative clinic near where I live in which there were B12 clinical trials for people with MS...and they were having "promising" results. I've also heard of B12 injections for Alzheimer's showing some benefit.
