One thing - I'm a bit embarrassed to say that I had no idea that vitamin D was a hormone/hormonal? Can someone explain that?
I`ve got twitching in my calf muscles too! Also googled and got a bit panicky about mnd! But wonder if it is to do with hrt, I`ve been on patches for nearly a month and one of the side effects is listed as muscle cramps so wondered if it might be causing the twitching? Or maybe yes a vitamin deficiency..?
