Shoulder Pain: Common Causes and How Physiotherapy Can Help

Why is the shoulder vulnerable to pain?

The shoulder allows a remarkable range of movement. Its ball-and-socket joint works with the shoulder blade, collarbone, muscles and tendons to position the arm. This mobility helps you reach overhead, behind your back and away from your body, but it also means that strength, control and coordination around the shoulder matter.

Symptoms may begin after a specific injury, a period of repetitive or unfamiliar activity, or a gradual change with no obvious single cause. Pain can also be influenced by stiffness, reduced strength, workload, sleep, general health and the way the neck, upper back and shoulder blade are moving.

What causes shoulder pain?

There are several possible causes of shoulder pain. Sometimes symptoms develop after an injury, while in other cases they gradually appear without a specific incident.

The location and nature of the pain can vary. You may experience pain at the front, side or back of the shoulder, stiffness, weakness or difficulty moving your arm. Common problems associated with shoulder pain include:

It is important not to assume that a particular symptom means you have a specific condition. Different shoulder problems can produce similar symptoms, so an appropriate assessment can help determine the most suitable approach.

Rotator cuff-related shoulder pain

The rotator cuff is a group of muscles and tendons that helps control and support the shoulder. Rotator cuff-related pain is a broad term used for shoulder symptoms commonly aggravated by lifting the arm, reaching, carrying or lying on the affected side.

You may notice pain when reaching into a high cupboard, placing a coat sleeve over the painful arm, fastening clothing behind your back or lifting a kettle. The shoulder may feel weak because movement hurts, even when the muscle itself is not seriously damaged.

Rehabilitation often involves understanding and modifying the current load, keeping the shoulder moving within a manageable range and gradually strengthening the shoulder and shoulder blade. The programme should reflect your starting point and response—not a generic list of exercises.

Frozen shoulder

Frozen shoulder commonly causes both pain and a clear loss of movement. Reaching overhead and behind the back can become particularly restricted, while night pain may disturb sleep. Symptoms can persist for months and sometimes longer.

The appropriate approach changes as the condition evolves. When pain is highly irritable, forceful stretching may make matters worse. Physiotherapy can help identify a suitable level of movement, maintain function, advise on comfortable ways to manage daily activities and progress rehabilitation as the shoulder becomes less painful.

Shoulder arthritis and joint pain

Arthritis may contribute to aching, stiffness, reduced movement, grinding or discomfort with loading the arm. Physiotherapy cannot remove arthritis, but it can help preserve useful movement, strengthen the muscles that support the joint and find more comfortable ways to approach valued activities.

Shoulder pain can also arise where the collarbone meets the top of the shoulder—the acromioclavicular joint. Symptoms may be particularly noticeable when reaching across the body, lying on the shoulder or performing heavier pushing and lifting tasks.

What does a shoulder physiotherapy assessment involve?

Nichola will begin by listening to how the problem started, how it has changed and which movements or activities affect it. Relevant medical history, previous injury, work, hobbies, sleep and your own goals all help shape the assessment.

Scans are not automatically required for every painful shoulder. Clinical assessment often provides enough information to begin appropriate management. If Nichola identifies features that need medical review or investigation, she can explain the appropriate next step.

Your personalised shoulder rehabilitation programme

There is no single exercise programme that suits every shoulder. The right dose and type of movement depend on your presentation, irritability, strength, function and goals. Your plan may include:

• Advice about your likely problem and factors that may be maintaining it
• Gentle mobility work where stiffness is limiting daily activities
• Progressive strengthening for the rotator cuff and shoulder blade muscles
• Gradual exposure to reaching, lifting, carrying or overhead activity
• Changes to desk, driving, sleeping or work positions
• Pacing strategies to avoid the cycle of doing too much and then stopping
• Hands-on treatment where it supports the wider rehabilitation plan
• A clear home exercise programme with realistic progressions

Why have physiotherapy in your own home?

A home visit allows Nichola to see how your shoulder problem affects real tasks in the environment where you perform them. Instead of recreating the situation in a clinic, the assessment can consider your actual desk, kitchen cupboards, chair, bed, stairs, garden tools or home exercise set-up.

At-home physiotherapy can be especially helpful when driving is uncomfortable, mobility is limited, you are recovering after surgery, or fitting clinic travel around work and family life is difficult. Appointments remain one-to-one and centred on your priorities.

Shoulder pain at work, while driving and at night

Desk and computer work

Prolonged desk work may not be the sole cause of shoulder pain, but a poorly arranged workstation can keep the arm reaching forwards and make symptoms harder to settle. Bringing the keyboard and mouse closer, supporting the forearm and changing position regularly may help.

Driving

Reaching for the steering wheel, changing gear or fastening a seat belt can aggravate symptoms. Adjusting the seat and wheel position may reduce unnecessary reach. If pain, weakness or restricted movement prevents safe vehicle control, do not drive and seek appropriate advice.

Sleeping

Night pain is common with several shoulder problems. Some people feel more comfortable on the opposite side with the painful arm supported on a pillow, or on their back with support beneath the arm. The best position is individual, and persistent night pain should form part of your assessment.

Should you rest a painful shoulder?

Complete rest is not usually the best answer for ordinary shoulder pain. Stopping all movement can add to stiffness, weakness and loss of confidence. It is often more helpful to temporarily reduce or adapt the most aggravating tasks while retaining comfortable movement.

The NHS advises staying active and gently moving the shoulder, while avoiding activities that clearly make symptoms worse and avoiding self-prescribed strenuous exercise. If you are unsure what is safe for you, an assessment can provide more specific guidance.

How long does shoulder pain take to improve?

Recovery varies according to the cause, how long symptoms have been present, health, daily demands and consistency with rehabilitation. Some problems settle relatively quickly; frozen shoulder and long-standing tendon or joint symptoms may take considerably longer.

Progress is not always a straight line. Useful signs of improvement can include better sleep, easier dressing, more comfortable reaching, improved strength or being able to do more before pain appears. Nichola can help set realistic milestones and adapt the programme if your response changes.

When should you seek medical advice for shoulder pain?

Arrange a GP or healthcare review if shoulder pain is worsening, has not started improving after around two weeks, or makes it very difficult to move your arm. Seek urgent advice from NHS 111 or an urgent GP service if:

• You develop sudden or very severe shoulder pain
• You cannot move your arm
• The shoulder or arm has changed shape or is badly swollen
• You have persistent pins and needles or loss of feeling
• The arm feels unusually hot or cold
• Pain followed an injury or accident such as a fall
• You have severe pain in both shoulders
• You feel feverish or generally unwell
