When should you see a Dr about twitching thumb?

You should see a doctor about a twitching thumb if the twitching persists for more than a few weeks, is accompanied by other symptoms like weakness or pain, or interferes with daily activities.

A doctor can help determine the underlying cause and recommend appropriate treatment.
