  1. Thumb twitching is most probably due to muscle overuse. Often anxiety and stress related. Could be due to computer mouse use. Occasionally, Carpal Tunnel Syndrome may cause thumb twitching. Also excessive caffeine and dehydration is to be considered. Of course, thumb twitching may be one of the signs sometimes associated with ALS, Epilepsy, MS, Lupus, or Parkinson’s, But most unlikely and not to be considered at this point. If twitching persists or worsens, consult a Neurologist.

  2. The twitching has been going on for a few days, My doctor has not referred me to a neurologist yet. There is no pain associated with it. I am extremely worried. Would the bloodwork have shown any immune system abnormalities?

  3. Can ALS, Epilepsy, MS, Lupus, or Parkinson’s be found in blood-work (CBC)?

  4. Hi.
    Thanks for the query..

    Thumb twitching at rest is uncommon and this can be caused be a variety of things, rarely it can indicate a nervous system problem but this tends to be the exception.

    More commonly thumb or muscle twitches at rest such as you have been noticing with your thumb recently, can be associated with stress, anxiety, caffeine intake, exercise, with twitching being seen after exercise, lack of sleep, nutrient deficiencies, and side effects of some medications including oestrogens, it can also sometimes indicate an electrolyte imbalance such as low potassium but this tends to be less common as well.

    Benign twitches such as those caused by the above are very normal and quite common and they can tend to come and go over a period of days.

    If the twitches become more long term, lasting over a period of weeks, or are associated with a loss of sensation, muscle, and weakness in the limb affected then a visit to a doctor would be advised..

    Hope this helps..
