Top Causes of Shoulder Discomfort and Pain
Discover the main causes of shoulder pain, from injuries like dislocations and sprains to chronic conditions such as osteoarthritis and bursitis. Learn symptoms and when to seek medical help for persistent discomfort in the shoulder area.

Shoulder discomfort can stem from localized issues or result from nearby muscles, tissues, and bones. As the most mobile and unstable joint in the human body, the shoulder's wide range of motion makes it vulnerable. For minor discomfort, remedies like pain relievers, heating pads, or ice therapy may help. However, persistent or severe pain warrants professional medical evaluation.
Common causes of shoulder pain include:
- Bone necrosis, a condition where bone tissue dies due to insufficient blood flow, leading to joint pain and restricted movement.
- Brachial plexus injuries affect nerves connecting the spinal cord to the shoulder, arm, and hand, often caused by trauma, tumors, or inflammation. Symptoms include loss of control and sensation.
- Osteoarthritis involves cartilage breakdown, resulting in joint tenderness, stiffness, and reduced flexibility.
- Shoulder dislocation occurs when the upper arm bone pops out of the socket, often due to falls. Symptoms include deformity, pain, swelling, and limited movement.
- Shoulder pain can sometimes signal a heart attack, typically affecting the left shoulder and radiating down the arm.
- Ligament overstretching or tearing causes sprains, leading to swelling and pain.
- Rheumatoid arthritis causes joint inflammation and damage, with symptoms like swelling, tenderness, and movement restriction.
- Tendon inflammation or irritation produces localized pain, tenderness, and mild swelling.
- A separated shoulder results from injury to the outer shoulder joint, causing weakness, swelling, and immobility.
- Bursitis involves inflammation of the bursae, leading to pain during pressure, stiffness, and swelling.
