question: I am a 19 year old female. For about a month or so I ve been getting twitching all over my body, mostly in my feet, legs, and arms. Recently my fingers have been twitching too. This morning my right index finger and thumb were moving nonstop for about 5 hours. My left hand gets shaky and my left middle finger feels stiff. I had blood work done a month ago for something unrelated and the only abnormal result was a vitamin D level of 17. Could this be the cause and if not what could be? Thank you.
