5 Causes of Shoulder Pain and Proven Treatment Solutions

Understanding Shoulder Pain: Common Causes and Effective Treatments

The shoulder is a complex ball-and-socket joint that allows for a wide range of motion. However, with this great mobility comes a lack of stability, making the shoulder highly susceptible to pain and injury. Shoulder pain is one of the most common complaints among patients, and it can be caused by a variety of issues, from poor posture to medical conditions. In this article, we’ll explore the most common causes of shoulder pain and how to treat it effectively.

Common Causes of Shoulder Pain: 

1. Poor Posture/Neck Origin:

Poor posture—whether sitting or standing—can lead to shoulder pain. If you have rounded shoulder posture, the shoulder joint is placed in a position where the bursa, muscles, and tendons can be pinched. Pinched nerves in the neck are a major cause of shoulder pain and weakness, often going unnoticed for years before turning into severe discomfort and pain.

2. Repetitive Activity:

While reaching overhead, the space between the shoulder tendon and the shoulder blade decreases. The tendons can then get pinched underneath the bony part of the shoulder blade. This pinching, often called impingement syndrome, can be painful.

Chronic shoulder pain often stems from prolonged, repetitive, or awkward movements. This type of pain is sometimes referred to as repetitive strain injury (RSI) or cumulative trauma disorder. This is common among people who work with their arm above the shoulder level, construction workers, teachers, painters, carpenters, and athletes. Sports like shooting a racket in badminton, overhead throwing, etc. will lead to repetitive strain on one group of muscles. This eventually leads to fraying of those muscles and may cause tears with minor trauma and rarely without trauma also.

3. Trauma:

Trauma can occasionally cause shoulder pain. Various types of accidents can lead to sudden injury, potentially resulting in broken bones, injured tendons and/or ligaments, or shoulder dislocation. Common traumatic incidents include: falling on an outstretched arm, landing on the side of your arm, falling from two-wheeled vehicles (e.g., bicycles, motorcycles), and making sudden, jerky movements while trying to avoid a fall. These incidents can lead to sudden injury and may break the bones or injure the tendons and/or ligaments of the shoulder. Such trauma can also dislocate the shoulder, resulting in significant shoulder pain.

4. Natural Aging or Degeneration:

One common degenerative condition affecting the shoulder is degenerative rotator cuff disease, which involves tendinitis and tears. This condition is particularly prevalent in older adults, with studies showing that approximately 30% of adults over 60 have a rotator cuff tear, increasing to 62% in those over 80.

Another common condition affecting the elderly is osteoarthritis of the shoulder, which can be one of the most painful shoulder conditions. Osteoarthritis is a degenerative condition that causes inflammation in joints throughout the body, including the shoulder. While it most often occurs in weight-bearing joints like the hip and knee, shoulder osteoarthritis can cause severe pain and loss of motion. Shoulder osteoarthritis occurs when the smooth cartilage covering the ends of the bones wears away, causing rough bones to rub against each other. This leads to irregular motion, bone spurs, and inflammation, resulting in pain and reduced shoulder mobility.

5. Medical illness

People with certain medical conditions are more susceptible to shoulder joint problems. Diabetes, in particular, significantly impacts the shoulder in various ways.

Diabetes also raises the risk of other shoulder conditions:

1. Rotator cuff disease: Diabetic patients have a higher prevalence of rotator cuff tears and tendinitis
2. Calcific periarthritis: An inflammatory process that can lead to calcium deposits in the joint capsule and surrounding tissues
3. Diabetic arthropathy: A condition where diabetes damages joints, potentially causing painful shoulders

Rheumatoid arthritis (RA) is another condition that significantly affects the shoulder. RA will cause muscle tendon inflammation of the rotator cuff and biceps. It can also cause hypertrophy and inflammation of the subacromial bursa – both of which are very painful conditions.

Other conditions affecting shoulder health include hypothyroidism and peripheral neuropathy.

Diagnosis and Treatment of Shoulder Pain:

Early examination by a physiotherapist or chiropractor can help diagnose the root cause of your problem before the pain, weakness, and stiffness of the joint worsen. A comprehensive physical examination of the neck and shoulder is beneficial. Depending on your condition, your practitioner may recommend:

1. Specific exercises
2. Postural correction tips
3. Self-mobilization techniques
4. Various therapeutic modalities such as:
   – Shockwave therapy
   – Laser therapy
   – Ultrasound therapy
   – Acupuncture

Additionally, massage therapy can help loosen the tissue around the shoulder joint and improve flexibility.
