Answer
Any number of conditions could be causing the problem. The most worrisome include vascular or nervous system diseases. A complete examination of the arm would provide more clues. This exam would include blood pressure and pulse in the left arm, compared to the right arm. Additionally, strength testing and evaluation of other components controlled by the nerves in the arm. Ultimately, an electrodiagnostic test may be necessary to get a more detailed picture of how the nerves are functioning. This condition may also be related to something as simple as a rotator cuff injury too. If you are having any other symptoms like fevers, weight loss or numbness, please see a doctor sooner rather than later to have the arm examined. That is your next step to a solution.
