I seem to add too many things all at once and then think nothing has helped.

I also cannot find doctors who will test me for nutritional deficiencies. I have not had a good diet for a long time, so I do think I could have nutritional problems. Why won't any doctors listen to me? My rheum has tested for B12 and D - but not any of the others. She doesn't believe in magnesium, says if I have a good diet I will get enough. (But I've read that overcoming a deficiency already there is quite hard, plus many fibro patients need magnesium).

How do I get these tests ordered? Are a lot of these ordered by neurologists?
