Twitching muscle: Muscle twitching is a nonspecific symptom. Typically due to some hyper-excitability of the muscle. Often these have no associated pain. Twitching can occur anywhere on the body or face. Common causes include stress, fatigue, caffeine or nicotine use, or electrolyte or hormonal imbalance. Something to bring to the attention of your doctor. Try to see if relaxing the arm helps. Good luck.
