Hello and thanks for your question. Twitching, pinprick feelings and vibratory sensations can come from many causes. Not drinking enough water and not having adequate vitamins are common causes. Make sure that you are drinking plenty of water and take a multivitamin/multimineral supplement daily. Avoid caffeine, alcohol and nicotine. If this does not resolve the problem, see your doctor for an exam and blood tests to help determine the cause.
