Shoulder condition
Rotator Cuff Tear
Also called: Torn Rotator Cuff
A rotator cuff tear is a partial or complete tear in one of the four tendons that hold the shoulder in place and let you lift and rotate your arm. It can happen suddenly from a fall or lifting injury, or build up over years of wear. The classic signs are shoulder weakness, pain when lifting the arm, and aching that is often worse at night.
Symptoms
A rotator cuff tear can come on suddenly or develop gradually. Common signs include:
- Weakness when lifting or rotating the arm
- Pain when raising the arm, especially overhead
- A deep ache that is often worse at night or lying on that side
- Difficulty reaching behind your back or up to a shelf
- A crackling or catching feeling when moving the shoulder
- A sudden tearing sensation at the moment of injury in acute cases
Causes
Tears fall into two groups - sudden injuries and gradual wear. Common contributors:
- Age-related tendon wear (most tears in people over 40)
- A fall onto an outstretched arm or the shoulder
- Lifting something too heavy or with a jerking motion
- Repetitive overhead activity from work or sport
- Previous shoulder injuries or impingement
- Reduced blood supply to the tendons with age
Tear vs strain: what is the difference?
| Rotator cuff strain | Rotator cuff tear | |
|---|---|---|
| Tissue | Tendon overstretched but intact | Tendon partially or fully torn |
| Weakness | Mild, temporary | Marked, often persistent |
| Pain | With movement, settles with rest | With movement and often at night |
| Recovery | Days to a few weeks | Weeks to months; larger tears may need surgery |
What helps a rotator cuff tear?
Many rotator cuff tears - especially partial ones - improve with rest, physiotherapy and pain relief rather than surgery. The priority is calming the pain, protecting the shoulder from overhead strain, and rebuilding the muscles that support the joint. A shoulder pain patch worn over the shoulder gives steady, drug-free relief you can wear day or night while it settles.
- Rest from overhead lifting and reaching while pain is sharp
- Ice in the early stage, then heat for stiffness later on
- Physiotherapy to strengthen the rotator cuff and improve posture
- Use drug-free relief - a shoulder pain patch over the shoulder
- Adjust sleep position - avoid lying on the painful side
- See a clinician if weakness is marked or pain does not settle
Frequently asked questions
Can a rotator cuff tear heal without surgery?
Many partial rotator cuff tears improve without surgery through rest, physiotherapy and pain relief. Small and moderate tears often become pain-free even if the tendon does not fully knit back together, because the surrounding muscles compensate. Full-thickness tears, or tears in active people, are more likely to need surgical repair. A clinician weighs the tear size, your age and activity level.
What is the difference between a rotator cuff tear and a strain?
A strain means the tendon is overstretched but still intact, so it causes temporary pain and mild weakness that usually settles in days to weeks. A tear means the tendon is partially or fully torn, bringing lasting weakness and pain that is often worse at night. Weakness that does not improve is the main clue that it is a tear, not a strain.
How do you sleep with a rotator cuff tear?
Avoid lying on the painful shoulder. Many people sleep best on their back with a pillow supporting the elbow, or propped slightly upright in a recliner. Hugging a pillow to support the arm can also ease strain. Night pain is common with cuff tears, so a warm compress or a pain patch before bed can help you settle.
Will a rotator cuff tear get worse if untreated?
It can. A small tear will not always grow, but continuing heavy or overhead use can enlarge it over time, and a bigger tear is harder to repair. Weakness and stiffness can also worsen if the shoulder is not moved and strengthened. Early assessment and gentle rehab give the best chance of avoiding a larger problem.
When should you see a doctor?
See a doctor if you cannot lift your arm, felt a tearing sensation during an injury, or have marked weakness that does not improve. Persistent night pain or shoulder pain lasting more than a few weeks also warrants assessment. A clinician can confirm the tear, sometimes with a scan, and advise whether rehab or surgery is right for you.
A quick, honest note. This guide is for general education and does not replace a diagnosis from a qualified clinician. mLab makes natural pain-relief patches and support devices - they can ease day-to-day discomfort, but they do not treat or cure this condition. If you cannot lift your arm, felt a tearing sensation, or have marked weakness, please see a doctor.
