I was opening a jar this afternoon and had trouble. A while later, my thumb started moving from side to side, at a fast rhythm, comes and goes for past 6 hours. Does anyone know what this could be caused by? Thank you.

Hello, it might be a lack of a certain mineral (calcium, magnesium, potassium etc) or too much caffeine, you also stressed the muscle. If it continues, get it checked out.
