I'm sorry to hear about your situation but I can identify with it somewhat. I was sick with a list of issues for 10 yrs before I really made any progress.
I'm certainly not saying that my situation is the same as everyone's but apparently I have/had a heavy metal problem.
Basically if you have a list of symptoms that medicine has not been able to resolve and those symptoms could be caused by heavy metals, doesn't is make sense to consider HMs?
Members of the chelaton groups sometimes start with a simple hair test and then look for either toxic elements or the effects of HMs, especially mercury on the essential elements. Some folks have strangely high levels of some essential element, especially copper.
