Plantar fasciitis is the most common cause of heel pain. It is commonly referred to as a heel spur, although a heel spur, or bony growth on the heel bone, develops as a result of plantar fasciitis. The condition occurs when the long, flat ligament on the bottom of the foot (plantar fascia) stretches irregularly and develops small tears that cause the ligament to become inflamed. This inflammation is most often caused by walking with an abnormal inward twisting of the foot, called pronation. Over time, this slightly abnormal step may increase tension on the plantar fascia and cause it to become inflamed.

Frozen shoulder (adhesive capsulitis) is a condition in which the tissues around the shoulder joint stiffen, scar tissue forms, and shoulder movements become difficult and painful. It can develop when you stop using the joint normally because of pain, other injury, or a chronic health condition, such as diabetes. Any shoulder problem can lead to frozen shoulder if you do not work to maintain its full range of motion.

Carpal tunnel syndrome is the term used to describe a specific group of symptoms (tingling, numbness, weakness, or pain) in the fingers or hand and occasionally in the lower arm and elbow. These symptoms occur when there is pressure on a nerve (median nerve) within the wrist (carpal tunnel). Carpal tunnel syndrome develops over time because of repetitive hand motions that damage muscle and bone in the wrist area.

Bursitis is inflammation of a bursa or bursae (more than one bursa), small fluid-filled sacs that cushion areas of friction around joints. Bursae contain synovial fluid that lubricates the joints.

Bursitis typically occurs as a result of overuse during physical activities or infection of the synovial fluid. If a bursa becomes infected or irritated from repetitive stress, it will cause pain and limited movement.

Bursitis is most common in the shoulder, knee, hip, elbow, or heel.
