What Are the Causes of Pain, Numbness & Tingling in the Left Arm?
The person walking into an emergency room with symptoms of pain, numbness and tingling in the left arm should be prepared for a series of tests to rule out a heart problem. This is not because a heart problem is the most common cause of these symptoms, but because it is the most serious of the possible causes, and the one that demands immediate medical treatment. Problems originating in the neck, shoulder or peripheral nerves can also cause these symptoms.
If you are experiencing serious medical symptoms, seek emergency treatment immediately.
