Your approach is important. Let me tell you a story that has impacted my approach to my health issues.
I was just starting out with a young family and had an old 1979 LeBaron and I was trying to get it certified, all it needed was a horn. Save the easiest for the last, right?
Sure wasn't hard to see what the problem was as the horn was a glob of rust. I drove 15 min to the wreckers and brought home a used horn. Didn't work, but that was OK as I then knew that it was the relay and took the horn back. Relay didn't work...but that was OK because I now had the problem narrowed down to the contacts in the steering wheel. But, I was wrong again.
I had to step outside the box. Know what was wrong with my car horn? All three things. It took me 2 days to figure that out. I have applied what I learned to many things in life.
For me, mercury toxicity was what upset the apple cart. But I also had to learn about methylation and that I was severely short of B12, Then I had to learn about Stealth Infections.
Our poor brains...when we get sick we lock in on goals and certain treatments. Our brains just want to focus on one thing it seems. We are taught to think this way. We have Internists, allergists, psychiatrists, dermatologists and so on.
It is truly a form of societal madness. We are integrated beings and only those who think that way will be able to help with multi-system problems.
Otherwise, chelation of metals made me sicker before I got better. Firing up methylation made me sicker before I got better and so did going after the infections. But that is me.
Stick with it though. You are a puzzle and you will figure it out in the end.
