nutritional problems can be pretty stealthy. i got away with my poor food choices, even though it was all individually wholesome and nutritious, for about 15 years. and then the wheels came off, and i had to learn.
people with vastly different eating habits can still end with the same collection of nutrional problems that researchers have repeatedly found in ms patients.
here is a short list of some really important ones to get you started - you might want to propose tests of these nutrients to your docs:
serum vitamin D3 - the correct metabolite to test is 25(OH)D3
serum vitamin b12
junk food is not a notable source of any of these components of the human body. also the tests are likely to come back 'normal' - that is not good enough. the 'normal' range includes both sick and healthy people. if you get these tests done and bring the results back i can help you figure out a regimen to get your levels into the optimal range.
for additional reading you might want to check out my signature links. by the way i think you could probably fix your anxiety and tremors with magnesium GLYCINATE. (other forms of magnesium supplements - for example 'natural calm' which is magnesium citrate) are more difficult for your body to absorb so you can end up with the runs). for future reference, spinach and swiss chard are excellent dietary sources of magnesium.
a couple years ago, i suggested my boss take magnesium to prevent menstrual cramping and she came to me later and asked if it could make her feel more calm. answer, yes. she commented to me a few months ago that it had really surprised her that the anxiety she had thought was just her basic personality, was actually a nutrient deficiency.
also, an interesting study (involving rats though), given the trauma aspect (experimental trauma, ick):
Effect of magnesium given 1 hour after head trauma on brain edema and neurological outcome http://thejns.org/doi/abs/10.3171/jns.1 ... alCode=jns
"The present study indicates that postinjury treatment with Mg++ attenuates brain edema formation and improves neurological outcome after experimental CHT."
