Arm pain (Brachialgia) is any discomfort, ache or soreness you feel anywhere between your shoulder and your fingertips. It can come on suddenly, such as after an injury, or build up gradually, and is sometimes felt in your arm even though the problem starts somewhere else, such as your neck or your heart.
