I would like to comment on your muscle weakness symptoms.

There is a vitamin deficiency that can be identified with a DNA test, involving Biotin. One of our neuropathy posters was just diagnosed with this:

The post after this one is one of mine expanding on that diagnosis:

according to one of janieg's links when a person is heterozygous (one gene affected) for this Biotin error, symptoms may only occur in adults after stressful activities and they may limp around otherwise with confusing symptoms. Children with the homozygous (both genes' missing) will present with symptoms in infancy or childhood.

It is something to think about. If you get the DNA testing, look for methylation errors as well.(affects B12 and folate activation) Our good ole FDA has blocked the OTC gene testers from evaluating the test for consumers, so you have to look up the results on the internet yourself to evaluate your various results.

Treatment for this involves high dose Biotin supplements. Biotin is B7 and normally consumed in micrograms. To treat this deficiency 5 to 10 milligrams are used once a day.
