hi and welcome to the forum
go to the doctor! ms or not, you should be getting the work done to nail down what is going on.
fyi you might do well to ask for a serum zinc test. if your level is low normal you'll match other ms patients. in order to match healthy controls you'd want your level to be high normal ie upper teens, ~18-19 umol/L
here's an example of depleted zinc levels (due to excessive tobacco use in this study but there are many ways to deplete zinc levels - tobacco is just one)
The relationship between serum trace element changes and visual function in heavy smokershttp://onlinelibrary.wiley.com/doi/10.1 ... 032.x/full
"Blood serum zinc (Zn) levels have been found to be [significantly] lower in patients with TTON (Tobacco-toxic optic neuropathy) than in normal subjects"
from table 1:
smokers 14.2 ± 1.8 ug/l
controls 16.1 ± 2.4 ug/l
controls are described as healthy, but the assessment of diet and lifestyle impacts on status of the nutrients under investigation are not fully unpacked via their surveyhttp://onlinelibrary.wiley.com/doi/10.1 ... x/full#ss6
if this study was controlled for other major influences on zinc status such as wheat and phytate intake, the control averages would likely be higher.
