If your shoulder hurts when you lift your arm out to the side, reach overhead, put on a jacket, or lie on that side in bed, one of the most common explanations is rotator cuff-related shoulder pain. This term is now preferred over older labels such as “impingement” because it better reflects the fact that shoulder pain is often multifactorial rather than caused by one single tissue being pinched. Current clinical practice guidelines place rotator cuff tendinopathy or rotator cuff-related shoulder pain among the most common reasons for pain with arm elevation (Desmeules et al., 2025).
The good news is that most non-traumatic shoulder pain of this type does not automatically mean surgery is needed. Current best evidence supports an education-led, exercise-based approach as first-line management for many people with this presentation (Desmeules et al., 2025).
The short answer
Pain when lifting your arm is commonly associated with:
- rotator cuff-related shoulder pain
- shoulder stiffness such as frozen shoulder
- load intolerance of the rotator cuff and surrounding tissues
- neck-related pain referring into the shoulder
- less commonly, an acute rotator cuff tear or other more significant
– (Desmeules et al., 2025; Lee et al., 2025).
That is why assessment matters. Two people can both have pain when lifting the arm, but one may mainly need progressive strengthening, while another may need help for stiffness, a neck-driven issue, or onward referral (Desmeules et al., 2025).
What is the rotator cuff?
The rotator cuff is a group of four muscles (Infraspinatus, subscapularis, supraspinatus, teres minor) and tendons that help centre the shoulder joint and assist with lifting and rotating the arm. When these tissues become less tolerant to load, irritated, weaker, or poorly conditioned for the demands placed on them, pain can develop during elevation and reaching tasks. Rotator cuff-related shoulder pain is therefore usually best understood as a problem of pain, function, strength, and load tolerance rather than just a “damaged tendon’ (Desmeules et al., 2025; Lewis, 2015).
Common reasons your shoulder hurts when lifting your arm
1. Rotator cuff-related shoulder pain
This is the most likely cause in many adults with painful lifting, especially if symptoms are aggravated by overhead movement, repetitive use, gym activity, or lying on the affected side. The 2025 rotator cuff tendinopathy clinical practice guideline supports exercise and education as core management (Desmeules et al., 2025).
2. Frozen shoulder
Frozen shoulder tends to present with both pain and true stiffness, particularly loss of external rotation and difficulty reaching behind the back. Recent clinical guidelines continue to support recognising frozen shoulder as a separate presentation because treatment priorities can differ from rotator cuff-related shoulder pain (Lee et al., 2025).
3. Neck-related pain
In some cases, what feels like shoulder pain may actually be referred from the neck. This becomes more likely if symptoms are accompanied by tingling, numbness, burning, or if neck movement clearly changes the pain pattern (Hage et al., 2026).
4. Acute rotator cuff tear
If symptoms started after trauma and there is sudden weakness or a marked inability to actively elevate the arm, an acute cuff tear becomes more important to rule out. Earlier surgical management of acute tears has been associated with better outcomes than delayed repair in some cohorts, which is why these cases warrant prompt assessment (Duncan et al., 2015).
Does this always mean I have a tear?
No.
One of the most important recent studies in this area showed that rotator cuff abnormalities on MRI are extremely common, even in people without shoulder symptoms. In a 2026 population-based study, rotator cuff abnormalities were present in 99% of adults aged 41 to 76, with poor agreement between MRI findings and symptoms (Ibounig et al., 2026).
In simple terms, scans often show changes that may be age-related or incidental rather than the true reason for pain.
This matters because many patients understandably panic when they hear words like “tear,” “degeneration,” or “wear and tear.” Current evidence suggests that a scan result on its own should not be used as the sole explanation for pain or the sole reason to push
toward surgery. Clinical examination and symptom behaviour still matter enormously (Desmeules et al., 2025; Ibounig et al., 2026).
Do I need a scan?
Often, not immediately.
For many cases of non-traumatic shoulder pain, current guidelines support starting with a good clinical assessment and a period of targeted rehabilitation first. The 2025 rotator cuff guideline notes that when imaging is needed to confirm a rotator cuff disorder, ultrasound may be preferred because of similar diagnostic properties to MRI for some cuff disorders and lower cost (a service we offer with our MSK Dr Khosla) (Desmeules et al., 2025).
That means the better question is usually not “Do I need a scan right now?” but “Would a scan change what I do next?” In many non-traumatic cases early management is still centred around education, activity modification, and progressive strengthening (Desmeules et al., 2025).
What actually helps?
Education and load management
The 2025 clinical practice guideline recommends patient-centred education, including discussion around prognosis, pain management, and modifying aggravating activities without falling into complete rest. This is important because under-loading and over-protecting the shoulder can both become barriers to recovery.
Exercise-based rehabilitation
Exercise is the backbone of treatment. The strongest modern recommendation is for an active rehabilitation approach aimed at improving pain, function, strength, endurance, and shoulder control. This is one of the most consistent findings across current shoulder rehabilitation literature. In our clinical setting we use strength testing as our outcome measures and range of motion – this is so we can closely monitor your progress and you can see this throughout the rehabilitation process (Desmeules et al., 2025; Lafrance et al., 2022).
Manual therapy
Manual therapy can still have a role, but usually as an adjunct rather than the whole treatment plan. The guideline supports spinal or shoulder-region manual therapy mainly for short-term symptom modification, particularly when it helps someone engage better with active rehabilitation (Desmeules et al., 2025).
Injections
Corticosteroid injections are not generally first-line for most non-traumatic rotator cuff-related shoulder pain, but they may have a role when pain is severe enough to significantly disrupt sleep or limit rehabilitation. For frozen shoulder specifically, more recent guidance continues to support intra-articular corticosteroid injection as a useful option, particularly when combined with physiotherapy this is usually done in the first 6 months in order to get the best possible results and reduce the effects of frozen shoulder (a service we offer with our MSK Dr Khosla) (Desmeules et al., 2025; Lee et al., 2025).
When should you get your shoulder assessed?
It is sensible to book an assessment if:
- pain has not settled
- you are struggling to train, work, sleep, or lift normally
- movement is becoming more restricted
- the arm feels weak
- you are unsure whether the issue is the shoulder itself, the neck, or something more
You should seek more urgent assessment if pain followed trauma and you suddenly cannot lift the arm, or if the shoulder pain is accompanied by systemic symptoms or features suggestive of non-musculoskeletal pathology. Reviews on painful shoulder assessment continue to emphasise screening for fracture, infection, malignancy, and referred visceral pain where the history suggests it (Artus et al., 2014).
How physiotherapy can help
A good physiotherapy assessment should help answer:
- what structure or presentation is most likely driving the pain
- whether the problem looks more like rotator cuff-related pain, stiffness, neck referral, or acute structural injury
- whether imaging or referral is actually needed
- what exercises and loading strategy will get you back to normal activity as quickly and safely as possible (Desmeules et al., 2025; Lafrance et al., 2022).
For most people, treatment should not be a generic sheet of band exercises. It should be a tailored plan based on symptom irritability, strength, movement quality, stiffness, work demands, gym goals, and sport or lifestyle needs. That is the point where a proper assessment tends to outperform self-diagnosis. This is where our expertise and experience in MSK injuries come into play, tailoring bespoke rehabilitation plans for you following outcome markers which are measurable so you can see your progress first hand!
Additional caveat!
Could MBST help shoulder pain?
MBST is a safe, non-invasive medical technology that supports recovery for people experiencing shoulder pain, particularly where pain, joint irritation, or degenerative change are contributing to ongoing symptoms. Working at the cellular level, MBST is designed to help calm inflammation, support the body’s natural repair processes, and create the optimal conditions for cells to function normally.
The most directly relevant clinical evidence comes from a 2025 study (Fishchenko et al) examining the combined application of MBST and McKenzie physical rehabilitation in patients with degenerative-dystrophic shoulder joint disease. Studies reported excellent or good clinical outcomes in 95% of patients, assessed using the Oxford Shoulder Score. A supporting literature review by the same group (Fischenko et al., Ukrainian Medical Journal, 2024) concluded that MBST is a promising direction in the management of degenerative-dystrophic joint diseases, with clinical studies reporting reduced pain intensity and improved functional activity. Broader evidence across musculoskeletal conditions is further supported by a 2021 scoping review (Schmidt, Debess & Møller 2021), which found a consistent, almost always significant beneficial effect of MBST on pain, joint function, and quality of life in osteoarthritis. As with many emerging medical technologies, building a robust evidence base takes time, and while these studies are small in scale, their findings are consistently encouraging and continue to grow in number.
MBST is designed to work as part of a complete care plan; complementing thorough clinical assessment, patient education, progressive exercise, and load management to support recovery and help restore function and confidence. It takes time to build a strong evidence base and the above studies.
The key takeaway
If your shoulder hurts when you lift your arm, the most likely cause is often rotator cuff-related shoulder pain, but not always. It could also reflect frozen shoulder, neck-related referral, or in some cases a more significant structural problem. The reassuring part is that most non-traumatic cases respond well to the right combination of education, progressive exercise, and sensible load management, and many do not need immediate imaging (Desmeules et al., 2025; Lee et al., 2025; Ibounig et al., 2026).
Not sure what is causing it?
If you are struggling to lift your arm, sleep comfortably, train normally, or simply want clarity on what is going on, a professional assessment is usually the quickest route to the right plan.
Book an assessment if you want a clear diagnosis, treatment plan, and rehabilitation strategy.
