Arm pain and injuries are extremely common. Arm pain can occur as a result of sports injuries, work injuries or simply everyday arm use. Arm pain can be a local injury or referred from your neck (cervical radiculopathy). This can result in neck-arm pain. Left arm pain can even be an early sign of a life-threatening cardiac issue, so an accurate history and diagnosis are important to the best management of your arm pain. It may even be life-saving!
