What if your shoulder isn’t ‘just tight’ — but the tendon is overloaded?”
Rotator cuff issues are some of the most common shoulder problems I see, especially in people who train, work at a desk, or do repetitive reaching. The rotator cuff (supraspinatus, infraspinatus, teres minor, subscapularis) helps keep the shoulder joint stable while your arm moves. When it’s irritated or torn, the shoulder can start to feel unpredictable.
Causes (why it happens)
Rotator cuff problems usually come from one of two routes:
• Repetitive overload: lots of overhead work (gym presses, pull-ups, swimming, tennis, volleyball), poor recovery, and training volume that increases too fast
• Sudden force: a quick, awkward movement, a fall, heavy lift, or “catching” something unexpectedly
Tendinopathy is more common than a full tear — but both need the right plan.
Symptoms and diagnosis (what people notice)
Typical signs include:
• pain when lifting the arm overhead or out to the side
• pain when lying on that shoulder at night
• weakness (pressing, reaching, carrying, even brushing hair)
• clicking/popping with movement
• reduced range of motion because the shoulder starts guarding
Diagnosis is usually based on your history + movement tests (range, strength, specific shoulder tests). Imaging (ultrasound/MRI) may be suggested if symptoms are persistent, severe, or follow a clear trauma.
Risks and complications (why you shouldn’t ignore it)
When a rotator cuff problem is left unmanaged, it can lead to:
• increasing irritation and pain with daily tasks
• progressive weakness and reduced shoulder control
• compensation patterns into the neck and upper back
• longer-term stiffness (in some cases, a frozen/stiff shoulder pattern)
• in some cases, degenerative changes and bone spur irritation
