Copper deficency diagnosis.

Hello all.
On the evening of Sept.12 2016 upon standing from kneeling in prayer I realized my left great toe was numb, not completely but the sensation was muted.. For lack of a better term. I thought it was odd, made mention of it to my husband, and thought no more on it. That is until the following morning when I woke up realized it was still numb. About an hour later I realized my right ear canal and right shoulder blade area was numb. I didn’t know what to make of it. I didnt want to make much of nothing but decided to go ahead and get checked out. I don’t think the Dr. believed what I was telling him because he kept arguing that I wasnt really numb if I had sensation, and I didnt know how else to describe it. He decided to check my thyroid levels and sent me on my way. I later made a follow up appt with my PCP. By this time the “numbness” was in both feet and was slowly progressing up my calves. He suspected MS and ordered more blood tests and sent me for an MRI Im not really sure what all was included in the blood test but it came back low Vit D. and the MRI was normal. So he started me on supplements. By Dec my symptoms were not getting better. It seems like everyday a new symptom would occur. I now have numbness on my hands, scalp, forehead, neck, back and bottom.
I decided to make another appt. with my PCP. Upon this visit it was clear my Dr. was at a loss, although he still made mention of podsible MS and referred me to a Neurologist. I dont have the neurologists’ notes but I’m pretty sure the only remarkable thing was the vibrations test upon examination. Which made me feel better because up till now I could’ve been making the whole thing up as far as anyone else is concerned. He told me low Vit would not cause my symptoms, and We discussed possible toxin exposure he ordered another blood test to check for antibodies and also a 24 hour urine test. The results came back low copper, and I was started on 3mg daily of Copper daily. The symptoms are still slowly progressing, I am now experiencing painful muscle spasms, zaps, and twitches, continued and worsening numbness, as well as fatigue. I feel i have slowed down considerably, though I am not having any noticible dificulty walking. I called the neurologist office this week to see if I could pick up my orders early so the results would be back in time for my follow up appt. in April. and made mention that I wasnt feeling any better. He prescribed that I now start 3mg twice a dayb instead of once.
Has anyone here been tested for Copper def. and if so what were the results. I am curious if there is something more going on here.
Thanks.
