I can relate to this one.
Have been dealing with this for a long time. 😔
The dysfunction and weakness sets in and compensations make it worse.
This is why we should address pain as early as possible.

Rotator Cuff Tendonitis
Rotator cuff tendonitis is a common shoulder condition caused by inflammation and irritation of the rotator cuff tendons, most often affecting the supraspinatus. These tendons help stabilize the shoulder joint and guide smooth arm movement. When repetitive stress, overload, or poor shoulder mechanics place excessive friction on the tendon, it becomes inflamed and thickened.
Biomechanically, the supraspinatus tendon passes through a narrow space beneath the acromion. During arm elevation, especially between mid-range angles, this space becomes tighter. If the tendon is swollen or irritated, it experiences increased compression and friction, leading to pain and movement restriction. Poor scapular control and muscle imbalance can further reduce this space and worsen symptoms.
Common causes include repetitive overhead activities, heavy lifting, prolonged poor posture, muscle weakness, and age-related tendon degeneration. Athletes, manual workers, and individuals with rounded shoulder posture are particularly at risk.
Symptoms typically include pain when lifting the arm, discomfort when reaching overhead or behind the back, night pain when lying on the affected shoulder, and reduced strength. Early stages may cause mild discomfort during activity, while advanced inflammation can produce constant aching.
If managed early, rotator cuff tendonitis responds well to rest modification, mobility work, rotator cuff strengthening, and posture correction. Improving scapular stability and restoring shoulder mechanics reduces tendon stress and prevents progression to tears or chronic impingement.
Protecting shoulder health through proper movement patterns, strengthening stabilizing muscles, and avoiding repetitive overload is key to long-term pain-free function.
