I have had chronic (left) neck fasciculations x 7months. Family doctor sent me to neurologist for initial exam. I did great in all areas, except the fasciculations continue, sometimes mild, sometime very aggressive and visually noticeable to the neurologist at the time of my first visit 3 months ago. Thankfully, he has ruled out ALS and MS, as I have no muscle weakness at all, but the fasciculations and mild muscle cramps on the left side of my neck continue. It is not painful, but certainly disturbing. He scheduled me for an MRI of my brain...just to rule out, I guess. He ordered lots of labs; Vitamin levels-folic acid, B12, iron, D, E, mag, B1. Also ANA, lead, RPR, and lupus. Not all results are back, but I got 2 calls from his office telling me most of my vitamin levels are low, especially iron, and I should visit my pharmacy to purchace and take the supplements. I started this today. I should add that I have also had thyroid studies done and they are normal, as well as chemistries. I should add that I am female, 59 yrs old. 5 6 133 lbs. ( I ve lost 11 lbs in 2 months, without trying. Appetite is weak. I don t take any medication-other than the vitamins I started today. I do smoke-not much. I drink alcohol - moderately.
Hello, The muscle weakness along with articulations is suggestive of a nerve related problem-can be a nerve root compression or irritation. This can also be related to electrolyte imbalance.  Hope I have answered your query. Let me know if I can assist you further.
