Hi Bearcat,
I am another one with muscle fasciculations. I was first diagnosed with MC in September 2014. In March 2015 I started noticing weird sensations in my right leg (like the feeling of a sock on my foot, tingling, slight pain in my thigh), I also noticed some trembling in my hands. At that time, I began taking the equivalent of Metanx. I switched PCPs in fall of this year as my former PCP was getting quite condescending and did not know what to do about all the various symptoms in my body that did not make sense according to her. The caves in Papua New Guinea did not cross her mind
My new PCP conducted tons of blood tests and also sent me for an EMG and nerve conduction study of the right leg this fall. Believe it or not, two days before my EMG/nerve conduction study, I was working at the computer and my left calf started twitching. It only twitched once or twice or I would have mentioned it to the physician who conducted the tests of the right leg. He told me that both the EMG and the nerve conduction study were absolutely normal. In the meantime, the twitching is quite frequent. Sometimes an eyelid, very often a muscle in either leg, thigh, calf, ankle, even the bottom of the feet, or the torso. There are days when it happens very frequently, and days where it doesn't happen at all. I was freaked out in the beginning, especially when a letter from the ALS association arrived, starting with "have you ever had muscle twitching...?"
There is a great website about muscle fasciculations:
www.aboutbfs.com. The topic "why you don't have ALS" is very informative:

So is the one written by a physician:

Basically, fasciculations are the least noticeable features for someone with a motor neuron disease, there are many much more severe symptoms that show up first.
Also, he recommended certain blood tests:
CBC, electrolytes (including Mg, Ca, PO4), TSH, B12, Folate, Cr, ALT, cholesterol (good to know anyway) +/- TTG/IgA (celiac disease) ONLY. If all clear, stop investigating and start ‘dealing’ with this annoying (but not pathological) disorder.
Since I had just had tons of blood tests and everything came back normal except for the vitamin D where I am still deficient despite taking it daily (I upped the dose since), I decided not to further investigate the fasciculations. The tremors have improved significantly. There were also days when I did not have any symptoms in my right leg. But, as Tex mentioned, if I discontinue the active vitamin B6/B9/B12 for a few weeks, I start having symptoms again. And yes, my B12 blood test was completely fine. But I don't think it truly represents the B12 in the cells.
Overall, I feel a lot better than a year ago, thanks to the great and wise advice received by all the wonderful people on this forum. I have no doubt that "all these weird symptoms" are associated with MC, and my hope is, that with lots more healing and time, they will vanish. It seems like one weird symptom goes away and another one turns up. But I try not to get too stressed out about it anymore.
