In brief: Urgent consult
The most threatening cause for this problem is lack of blood to the arm. That could happen when the artery that supplies blood to that arm is occluded.
The symptoms would manifest initially only when the use of the arm makes the decreased supply insufficient to cover the increased demand but it'll be enough when the arm is resting. See a doctor as soon as possible to confirm/rule out this diagnosi.
