Re: Can anyone tell me what the problem(s) is/are by looking at my symptoms?:

Things to consider:

Need more magnesium, including Mg sulfate (epsom salt). Some like the more subtle effect of a foot bath. I'd start with Mg glycinate + Epsom Salt.

Support for adrenal cortex hormones.

Need more vitamin K? Need support for bile flow or stomach acid to absorb fat soluble vitamins?

Glucosamine sulfate for joints?

Do you just happen to have all of these problems as unrelated issues or are there one or a few underlying factors contributing to most of them?

Dr Mark Hyman reported many of your symptoms. He was disabled as a young doctor. In his book he wrote that he went to ten other doctors before someone realized heavy metals were a major factor.

Although I like Hyman and am certainly grateful to him, I chose Cutler's detox protocol. It has gone pretty well so far.
