I am having constant muscle twitches every day for a year. It is manageable on most of the days. But still, it affects my daily life. I consulted a doctor and she told me that I have vitamin D deficiency. I was prescribed vitamin D. I am taking it still now. But still, it seems unusual. I have them often every day. I want to know whether my kidneys are unable to process vitamin D properly. Can I have any other health issues? I do not have any diseases, viruses, and other health issues. I came to a point where I have to take sleep medication every day because my spasms are too bad.
