I have seen many, many doctors in the past three years, both allopathic and naturopathic. I had so many tests done you would not believe. I think every part of my body had been poked or probed at some point in the last 3 years. This test I had done recently was the first test that has ever showed anything wrong, otherwise, I am told I am in perfect health. Also, it was not my LIVER that was functioning at 20%, but my GALLBLADDER. My liver is fine as far as tests are concerned, but my naturopath does feel that I have a congested or sluggish liver. I am definitely not trying to diagnos myself. Like I said, all testing shows my body to be very healthy in every other way, just the gallbladder thing. For the past 3 years, since starting to see many physicians only a week or two after this started, I have been going through treatment for parasites, yeast and mercury toxicity, mostly because those were the only things that were ever found to be wrong.
