Fasciculations in arms (twitching) Report

A fasciculation (or "muscle twitch") is a small, local, involuntary muscle contraction visible under the skin arising from the spontaneous discharge of a bundle of skeletal muscle fibres. Fasciculations have a variety of causes, mostly benign, but can also be due to disease of the motor neurons.
