I inserted this in another post but thought someone might know this one. For the past few weeks myright thumb has been twitching or moving like a twich all through the day. I also noticed that my right foot also has tbe same movement in the big toe and and in the foot like restless leg. It did it so little before I never thought much about it but now its doing it often not only during the night but the day too. My right hand and arm and leg is dominant so im wondering if just overuse cold cause this or is it something serious that could be bad. Its upsetting to me and makes me nervous. Anyone else have this and is it anxiety related?
