Hi All, I've been having alot of the same symptoms as what has been described with all of you with MS and the vit D deficiency also.  I've been diagnosed with the vit D deficiency for almost a year now.  Thought I was losing my mind with the muscle aches, fatigue, and brain fog.  I'm a student working on my masters degree 45 years old.  It almost totally debilited me.  I'm glad we finally found it, but now the doc tells me I have lesions on my brain on a recent MRI.  I have confusion, dizziness, staggering when walk, sometimes vomiting from nausea caused by dizziness, some tingling in arms or hands, very bad headaches, an blurry vision.  This all has come and gone for years and just stays longer now.  Apparently, it may be MS, but have been referred to a neurologist for more testing.  I will tell you all that I was the healthiest when I sought the help of an OMD (practicioner of Chinese medicine)  The acupuncture, herbs, diet change, and weight lose helped me so much I did not have any of the symptoms.  I'm going to go back to the Chinese medicine again and restrict my diet, try to take of lbs, begin the acupuncture again, and start taking herbs to build my immune system up again.  I'm also going to do some research of MS and vit D deficiency and Chinese medicine.  I owe it to my fiance to be the healthiest and independent person I can be.  For now I'm going to put grad school on the back burner until my health improves.   Jan
