Can The Right Arm Hurt During A Heart Attack?

Does your right arm start hurting if you are about to have a heart attack?

Answer

This is what it says about this in the Merck Manual: "Pain produced by a heart attack may feel as if it is coming from the arm because sensory information from the heart and the arm converge on the same nerve pathways in the spinal cord." So basically the arm pain is caused by the body reacting to pain from the heart that's coming through the same nerve pathways. If this convergence happens in a way that affects the right side, then it does sound as if it could come from the right side.
