Old shoulder pain

The shoulder is one of the most complex and mobile joints in the human body, built from three bones: the humerus, scapula, and clavicle. Its supported by four joint interfaces: the glenohumeral, sternoclavicular, acromioclavicular, and scapulothoracic joints. This design allows for an extensive range of motion but comes at the cost of stability, making the shoulder especially prone to injury. Stability is provided by the rotator cuff muscles (supraspinatus, infraspinatus, teres minor, and subscapularis), which compress the humeral head into the glenoid socket, as well as by larger muscles like the deltoid, trapezius, and pectoralis major that assist with movement and joint control. The muscles are intertwined in with the shoulder labrum which compress the shoulder into socket with muscle contractions. Common movements include flexion, extension, abduction, adduction, and internal and external rotation. Because of its structure, the shoulder accounts for nearly half of all joint dislocations, with anterior dislocations being the most frequent due to no bony structures on the anterior side of the shoulder. The anterior portion is also the thickest part of the shoulder labrum. It is also vulnerable to overuse injuries such as rotator cuff tears, bursitis, and labral damage. Treatment often begins with conservative approaches like rest, physical therapy, and anti-inflammatory medications, but surgery may be needed in cases of recurrent dislocation, severe tissue damage, or advanced arthritis. Understanding the balance between mobility and stability is key to maintaining shoulder health and managing injuries effectively.

If your shoulder still bothers you after a past dislocation, your best bet is to rebuild the stability around the joint with specific exercises—not just general lifting. Start with isometric external rotation: stand with your elbow bent at 90° by your side, press the back of your hand gently into a wall without moving your arm, and hold for 10 seconds—repeat 10x. Next, add scapular retraction (pinch your shoulder blades together and hold for 5–10 seconds), and prone Y and T raises lying on your stomach to target your rotator cuff and shoulder blade muscles. Lastly, and the best way to strengthen the rotator cuff, is Sidelying External Rotation. This targets the rotator cuff the most without activating the other muscles as much in the shoulder. As you get stronger, use a resistance band for external rotations and rows to train proper movement and control. Avoid heavy overhead lifting for now, and focus on slow, controlled reps. If these exercises hurt or your shoulder still feels unstable, it’s a good idea to check in with a PT who can tailor the program to your shoulder’s needs.

If your shoulder has ever dislocated, you know how intense and sudden that pain is, but what’s more frustrating is how it can keep bothering you even after it's been put back in. A shoulder dislocation, especially the common anterior type, can stretch or tear key stabilizers like the labrum or rotator cuff. Even after relocation and rest, the damage to soft tissue can leave the joint unstable, leading to recurrent dislocations or that nagging, random pain when you reach overhead or when lifting in the gym. This is especially common in younger, active individuals—some studies show that over 90% of people under 20 who dislocate their shoulder once will do it again without surgical repair. Physical therapy can help retrain the surrounding muscles to stabilize the joint, but in some cases, persistent pain is a sign of underlying issues like labral tears, capsule laxity, or subtle nerve irritation that weren’t fully addressed.
