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.
Conditions that result from overuse or continual stress on your shoulder include the following:
- Bursitis - a painful condition that affects the small, fluid-filled "bursae" sacs that cushion the bones, tendons, and muscles.
- Tendinitis - inflammation or irritation of a tendon that attaches muscle to bone.
- Rotator Cuff Tear - when the tendon pulls away from the arm bone
All of these conditions can make routine activities very 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.
