Your shoulder is one of the most mobile joints in your body—and also one of the most vulnerable. At the center of this complex joint is the rotator cuff, a group of four muscles and tendons that stabilize your shoulder and allow you to lift and rotate your arm. When something goes wrong, even simple daily tasks like reaching overhead or getting dressed can become painful.
Common Causes of Ongoing Shoulder Pain:
◼️Dislocation
A shoulder dislocation happens when the upper arm bone pops out of its socket. This injury often causes sudden, intense pain, swelling, bruising, and weakness. Immediate medical attention is usually required.
◼️Separation (AC Joint Injury)
A hard fall or direct blow can damage the acromioclavicular (AC) joint, where the collarbone meets the shoulder blade. This may result in pain and a noticeable bump on top of the shoulder.
◼️Fractures
Broken bones in the shoulder—most commonly the clavicle or upper arm bone—are typically caused by falls or high-impact trauma. Severe pain and difficulty moving the arm are common symptoms.
◼️Labrum (Cartilage) Tear
The labrum is cartilage that helps cushion and stabilize the shoulder joint. Repetitive overhead motion or injury can cause tears, leading to catching, grinding, or locking sensations.
◼️Rotator Cuff Tear
A torn rotator cuff can develop from overuse, aging, or acute injury. Symptoms often include weakness, nighttime pain, and a crackling feeling when moving the arm.
◼️Frozen Shoulder (Adhesive Capsulitis)
Frozen shoulder causes stiffness and limited range of motion as thickened tissue tightens around the joint. The condition typically develops gradually and can take months to improve.
◼️Impingement & Bursitis
Repetitive overhead movements can irritate tendons or inflame the bursa (a small fluid-filled sac that reduces friction). This often causes pain during movement, especially when lifting the arm.
Other Conditions That Can Cause Shoulder Pain:
◼️Arthritis
Both osteoarthritis and rheumatoid arthritis can cause stiffness, swelling, and chronic discomfort in the shoulder joint.
◼️Referred Pain
Sometimes shoulder pain doesn’t originate in the shoulder at all. Problems in the neck, gallbladder, liver, or heart can cause discomfort that radiates to the shoulder. Sudden shoulder pain accompanied by chest tightness or shortness of breath may signal a heart attack—seek emergency care immediately.
◼️Tendinitis & Bone Spurs
Inflamed tendons or extra bone growth can restrict movement and lead to persistent pain, especially with activity.
