Shoulder Pain: Rotator Cuff, Impingement and Frozen Shoulder
Shoulder pain is rarely subtle. It shows up when you reach for a seatbelt, hang out washing or roll onto that side at 3am. The two patterns we see most often are rotator cuff related pain and frozen shoulder, and they behave very differently, so telling them apart changes what you should do next. This page is general information, not a diagnosis. If anything here matches your symptoms, an assessment is the sensible next step.
What is Shoulder Pain?
Rotator cuff related shoulder pain describes irritation of the tendons that control the shoulder, often with weakness and a painful arc of movement. Frozen shoulder (adhesive capsulitis) is a progressive tightening of the joint capsule, where movement is lost in every direction, including when someone else moves the arm for you.
Typical Symptoms
- Pain on the outer upper arm rather than pinpointed at the joint
- A painful arc when lifting the arm to shoulder height
- Difficulty reaching behind your back or into a back pocket
- Night pain lying on that side, one of the most common reasons people finally book
- With frozen shoulder, stiffness that limits movement even when relaxed
Common Causes & Triggers
- A sudden increase in overhead or loaded activity, such as decorating or a new gym programme
- Tendon capacity not keeping up with demand, common from the mid forties onward
- A fall onto the arm or an awkward heavy lift
- Post-operative or post-immobilisation stiffness
- Frozen shoulder can begin with no clear trigger, and is more common in people with diabetes or thyroid conditions
How We Treat Shoulder Pain at Bluebell
- 1
Assessment to separate cuff related pain, stiffness dominant presentations and referred pain from the neck.
- 2
Progressive loading for the cuff and shoulder blade muscles, which is the best evidenced treatment for tendon related shoulder pain.
- 3
Hands-on treatment and range work for stiffness dominant shoulders, matched to the stage.
- 4
Pain management support so you can sleep, including position advice.
- 5
Clear onward referral if we think imaging, injection or a surgical opinion is genuinely needed.
Honest Recovery Timeline
Rotator cuff related pain commonly improves over six to twelve weeks with consistent loading, and needs the strength work continued beyond the point pain stops. Frozen shoulder is much slower and honesty matters here: it typically runs over many months, and physiotherapy is aimed at maintaining what movement you have, easing pain and speeding the recovery phase rather than forcing it.
When Shoulder Pain Needs Urgent Medical Attention (Not Physio)
- •Shoulder pain after significant trauma with obvious deformity or inability to move the arm, go to A and E.
- •Chest pain, jaw or left arm pain with breathlessness, sweating or nausea, call 999 as this can be cardiac.
- •Fever, hot swollen joint or feeling generally unwell, urgent medical review.
- •Unexplained weight loss, a history of cancer, or a lump in the shoulder or armpit, see your GP.
Shoulder Pain — Common Questions
How do I know if it is frozen shoulder?
The clearest sign is loss of movement in all directions, especially rotating the arm outwards, even when someone else moves it. Cuff problems usually hurt through range rather than blocking it.
Should I rest a painful shoulder?
Complete rest tends to make both stiffness and weakness worse. We usually modify what aggravates it while loading it in ways that do not flare it.
Do I need a scan or an injection?
Most shoulders improve without either. Injections can be useful to open a window for rehab in very painful cases, and that is a decision made with your GP or a consultant.
Why is it worse at night?
Lying on the shoulder compresses irritated tissue and there is nothing else competing for your attention. Position changes and pillow support often help while treatment takes effect.
Can neck problems cause shoulder pain?
Yes, and it is commonly missed. Part of the assessment is checking whether your neck is referring pain into the shoulder.
