Causes of Shoulder Pain
Effective treatment for shoulder pain depends on pinpointing the cause. Although there are many conditions that contribute to shoulder pain, these are the most common.
- Rotator Cuff Tendinitis or Bursitis
Tendinitis develops when shoulder tendons become inflamed and sore, often from repetitive stress or overuse. Bursitis happens when the fluid-filled sac protecting the shoulder joint becomes inflamed.
Both osteoarthritis and rheumatoid arthritis can cause shoulder pain, stiffness, and mobility limitations. Osteoarthritis is caused by the deterioration of joint cartilage. Rheumatoid arthritis occurs when the body’s own immune system attacks the joints, causing pain and inflammation.
- Pinched Nerve Shoulder Pain
Pinched nerves in the neck can cause pain, numbness, and tingling in the shoulder joint. Nerve roots extending from the spinal cord to the rest of the body become compressed, usually by herniated disc, osteoporosis fractures, or other conditions that affect the cervical spine.
With shoulder pain and a pinched nerve, patients often report a “pins and needles” sensation in their shoulders, arms, and hands. The sensation doesn’t change when they move their shoulders because it originates in a different part of the body.
