Shoulder
Rotator Cuff Tendinopathy & Impingement
Also called: Shoulder tendinitis, subacromial pain
Irritation of the cuff tendons that steer the shoulder's ball in its shallow socket — the most common cause of shoulder pain. Driven by load spikes, overhead volume, posture, and how the shoulder blade moves. Responds impressively to progressive exercise; most cases never need anything more invasive.
Common signs
- Outer-shoulder/upper-arm ache, worse reaching overhead or behind the back
- A painful arc raising the arm to the side
- Night pain lying on that shoulder
- Weak or painful rotation strength testing
Seek help now if
- Sudden weakness after trauma (acute tear — assess promptly)
- Hot swollen joint with fever
- Rapidly progressive weakness or wasting
If any of these is sudden or severe, call 911 or go to an emergency room. For the others, get examined before you start self-care.
What to do first
- Get examined — cuff, biceps, AC joint, neck referral, and frozen shoulder present similarly and are treated differently
- Modify (don't eliminate) overhead volume; keep the shoulder moving through comfortable ranges
- Begin cuff and scapular loading — exercise is the first-line, best-evidenced treatment
The longer road
- A 12-week progressive program (cuff rotation work, scapular control, posture, thoracic mobility) is the standard of care
- Stubborn cases: re-examine the diagnosis, training loads, and neck contribution before escalating
- Injections can quiet a hot shoulder for rehab to proceed — they treat symptoms, exercise treats causes
Natural healing options we use
- Progressive cuff and scapular strengthening
- Manual therapy for cuff, pec minor, posterior capsule
- Chiropractic care for cervicothoracic mechanics (the shoulder's foundation)
- Attended e-stim and PEMF; collagen and omega-3 support
About imaging
Not needed initially in most; ultrasound/MRI when trauma, significant weakness, or failed quality rehab raises tear questions.
Daily self-care
- Daily band external-rotation and row work
- Posture breaks and thoracic extension during desk hours
- Modify sleep position (pillow support, avoid the bad side)
