MSD Injuries and Disorders
Shoulder
Shoulder pain and injuries are usually the result of overworking the shoulder. When you keep your arm raised above your shoulder (or keep your arm stretched out), your shoulder begins to ache after a short time. It tires easily.
Continual stress on your shoulder can lead to suffering from bursitis and tendinitis. Another shoulder injury is the rotator cuff tear which can make routine activities difficult and painful.
Neck
The neck is a complicated structure composed of seven bones called cervical vertebrae, one below another. It also has cartilage, nerves, muscles, and ligaments. When you keep your neck bent forward or backward, or bend it frequently, the muscles work harder and the ligaments flex and stretch. Eventually the ligaments can partially tear, resulting in neck sprain.
