Thumb started twitching today, you can see it twitch on and off should I be worried no other symptoms?

Watch and wait. You may watch and wait. If the twitching spreads to other parts of the body or is still there three weeks from now, it would be time to see a doctor. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.
