Injuries are the most common cause of shoulder pain.

Minor shoulder problems, such as sore muscles, aches and pains, are common. Shoulder problems develop from everyday wear and tear, overuse or injury. They can also be caused by the natural process of aging.

Shoulder problems can be minor or serious. Symptoms may include pain, swelling, numbness, tingling, weakness, changes in temperature, color or in your range of motion. Shoulder injuries most commonly occur during sports activities, work-related tasks, falls or projects done around the home. Home treatment can often help relieve minor aches and pains.

Your shoulder joints move every time you move your arms. To better understand shoulder problems and injuries, it’s helpful to review the anatomy and function of the shoulder. The shoulder is a ball-and-socket joint with three main bones: the upper arm bone (humerus), collarbone (clavicle) and shoulder blade (scapula). These bones are held together by muscles, tendons and ligaments. The shoulder joint has the greatest range of motion of any joint in the body. Because of this mobility, the shoulder is more likely to be injured or cause problems. The acromioclavicular (AC) joint, which lies over the top of the shoulder, is also easily injured.

A sudden injury may occur from a fall on an outstretched arm, a direct blow to the shoulder or abnormal twisting or bending of the shoulder. Pain may be sudden and severe. Bruising and swelling may develop soon after the injury. If nerves or blood vessels are injured or pinched during the injury, the shoulder, arm or hand may feel numb, tingly, weak or cold, or it may look pale or blue. Acute injuries include:

• Bruises (contusions), which occur when small blood vessels under the skin tear or rupture, often from a twist, bump or fall
• Injuries to the tough, ropy fibers (ligaments) that connect bone to bone and help stabilize the shoulder joints (sprains)
• Lesiones de las fibras duras y elásticas que conectan el músculo con el hueso (tendones).
• Tirones musculares (distensiones)
• Injuries to nerves, such as brachial plexus neuropathy
• Separation of the shoulder, which happens most often from a blow to a shoulder or a fall onto a shoulder or outstretched hand or arm
• Damage to one or more of the four tendons that cover the shoulder joint (torn rotator cuff), which may occur from a direct blow to or overstretching of the tendon
• Huesos rotos (fracturas), que se producen cuando un hueso se tuerce, se golpea directamente o se usa como refuerzo contra una caída.
• Pulling or pushing bones out of their normal relationship to the other bones that make up the shoulder joint (subluxation or dislocation)

You may have a shoulder injury that occurs from overuse if you do not recall having a specific injury, especially if symptoms began gradually or during everyday activities. Overuse injuries occur when too much stress is placed on a joint or other tissue, often by overdoing or repeating an activity. Overuse injuries include:

• Inflammation of the sac of fluid that cushions and lubricates the joint area between one bone and another bone, a tendon or the skin (bursitis)
• Inflammation of the tough, ropy fibers that connect muscles to bones (tendinitis). Bicipital tendinitis is inflammation of one of the tendons that attach the muscle (biceps) on the front of the upper arm bone (humerus) to the shoulder joint. The inflammation usually occurs along the groove (bicipital groove) where the tendon passes over the humerus to attach just above the shoulder joint.
• Muscle strain
• Frozen shoulder (adhesive capsulitis), which is a condition that limits shoulder movement and may follow an injury.
• Abrasion or inflammation of the rotator cuff tendons (impingement syndrome) from overhead arm movements that cause tendons to rub or scrape against a part of the shoulder blade (acromion).

Acute and overuse injuries are common causes of shoulder symptoms. Less common causes of shoulder symptoms include:

• Muscle tension or poor posture
• Pain that is coming from somewhere else in your body (referred shoulder pain)
• Breakdown of the cartilage that protects and cushions the shoulder joints (osteoarthritis)
• Calcium buildup in the tendons of the shoulder
• An irritated or pinched nerve or a herniated disc in the neck
• Infection in the skin (cellulitis), joint (infectious arthritis), bursa (septic bursitis) or bone (osteomyelitis)
• Invasive cancer that has spread to the bones of the shoulder or spine
• Abuse (any shoulder injury, especially a dislocated shoulder, that can’t be explained, does not match the explanation or occurs repeatedly may be caused by abuse)

Treatment for a shoulder injury may include first aid measures, physical therapy, medicine and, in some cases, surgery. Treatment depends on:

• La localización, el tipo y la gravedad de la lesión
• El tiempo transcurrido desde que se produjo la lesión
• Your age, health condition and regular activities, such as work, sports or hobbies
