Sounds strange doesn't it? But I have googled as I don't understand why it's happening, but today they haven't stopped with the intermittent vibrating. I have no pain but it's annoying. I've read that it could be a vit b12 deficiency or I need to have a break from my vitamins that I'm already taking which is magnesium citrate and cod liver oil. Anybody else suffer or can give me advice please?
