My nerves have been twitching my muscles can it be caused from alotstress? They are not painful but very annoying. (Upper arm, below jaw, lower leg.)

Twtiches. Please start by seeing your doc to rule out/identify any underlying medical condition. Magnesium supplements are sometimes used to help w/twitches. Jigsaw brand magnesium is a respected brand but there are others. Peace and good health.
