Dear All, I was experiencing a lot of twitching recently esp. In my left feet (like all time buzzing) right arm and right eye-lid. I was tested for MS last month (negative) and did have one EMG in my leg (negative) but my doctor told me I did have a very high level of vitamin B6 in my brain fluid. Can this cause fasciculations? Of course Im still scared it can be something seeious, so if anyone have experience with B6 Toxicity and same symptoms I would be reallyy grateful for feedback.
