The common causes of muscle twitching like the one that you are describing are ..
- stress/ anxiety
- drugs (caffeine- excess coffee)
- electrolyte imbalalnce (low potassium)
- drugs (estrogen, diuretics, steroids)
Rarely it can be a sign of the beginnign of a nerve disease.. hence show to a doctor if the symptoms do not improve over the next few days, while you should take plenty of fluids and a vitamin supplemetn (like centrum) in the meantime..
