Musculoskeletal and Repetitive Strain Injuries
Many people feel like their left arm is aching all day because of doing the same thing over and over. This can lead to swelling in tendons or bursa, like tendinitis or bursitis. When you feel left arm sore pain, it’s usually from the shoulder or elbow.
