I have a twitch in my left thumb-it occasionally moves on it own?

I have a twitch in my left thumb-it occasionally moves on it own. My doctor has run CBC blood work and hospital has run bloodwork and all results came back fine. I suffer from anxiety and sometimes depression. Why is my thumb still twitching? Is this a sign of MS, Lupus, or Parkinson’s’?

General Information: I have a kidney disease (FSG) im not sure if this has anything to do with the twitching. My doctor doesnt seem to worried. I have not gone to see a neurologist yet.

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.
