Why is the top of my left arm trembling/spasaming been going for over 2 days now?

Twitching: It may be caused by an irritable nerve or muscle. Deficiency of calcium,magnesium and electrolyte disturbance can be a cause. Avoid caffeine and see your MD if symptoms persist. Tests will be ordered. A neurologist can be consulted as needed.
