I haven't had anything checked. I haven't been to a medical doctor for 15 years. I did see a heath practitioner for a year, with no results. He tested me for everything by using some instrument with a blunt probe that he pressed onto some acupuncture points. There was a metal tray also. He would put viles of things to test me for allergic reaction. I think it was called NEAT, similar to NAET. $100 per visit. Nothing showed up. Not in metals, foods, fungi, etc. I'm allergic to pineapple; so no bromelain. I'm also allergic to banana, egg whites, milk, and red kidney beans. Still, he did not help my sinuses, constipation, cold hand/feet. That's all I care about right now. It make for poor quality of life.
I'm really counting on Iodine therapy solving my allergic reactions.
I have heard of Wilson's Syndrome. I though I had that for a while too.
