Shoulder stiffness and pain: causes and when to seek help

Shoulder stiffness and pain are common complaints that can limit your daily activities, from reaching overhead to lifting objects or sleeping comfortably. The causes range from minor muscle strain to conditions requiring professional assessment. Understanding what might be causing your symptoms and recognising when to seek help can guide you towards the right support.

What causes shoulder stiffness and pain?

Shoulder stiffness and pain can develop for several reasons:

• Muscle strain or overuse: Repetitive activities, poor posture, or sudden exertion can strain the muscles and tendons around your shoulder.
• Frozen shoulder (adhesive capsulitis): The tissue surrounding the shoulder joint becomes inflamed and tight, causing progressive stiffness and discomfort.
• Rotator cuff injury: The group of muscles and tendons that stabilise your shoulder may be strained, torn or inflamed.
• Shoulder impingement: Structures within the shoulder joint become compressed, causing pain during certain movements.
• Arthritis: Wear and tear or inflammatory conditions can affect the shoulder joint.
• Bursitis: Small fluid-filled sacs (bursae) around the shoulder become inflamed.
• Shoulder dislocation or instability: The shoulder joint may slip out of place or feel unstable.
• Trauma or injury: Falls, accidents or direct impact can cause acute pain and stiffness.

How shoulder pain and stiffness develop

Shoulder pain may start suddenly after an injury or develop gradually over weeks or months. Stiffness often worsens when you avoid using your shoulder, as reduced movement can lead to tightness. Pain may be sharp, dull, aching or burning, and may radiate down your arm or into your neck.

When to seek professional assessment

You should consider seeing a healthcare professional if:

• Pain or stiffness persists for more than a few weeks despite rest and over-the-counter pain relief.
• Stiffness is progressively worsening and limiting your daily activities.
• You have severe pain, especially after an injury or fall.
• You experience weakness, numbness or tingling in your arm or hand.
• Your shoulder feels unstable or as though it might slip out of place.
• You have signs of infection, such as warmth, redness or fever alongside shoulder pain.

A healthcare professional can examine your shoulder, discuss your symptoms and medical history, and arrange imaging or other tests if needed to identify the underlying cause.

What you can do to help manage symptoms

In the short term:

• Rest your shoulder from activities that trigger pain.
• Apply ice for the first 48 hours after an acute injury, then heat if helpful.
• Use over-the-counter pain relief as directed on the packaging.
• Support your arm with a sling if movement is very painful.

Longer-term management:

• Gentle movement and stretching, as tolerated, to maintain mobility.
• Physiotherapy or specialist upper limb therapy to strengthen muscles and improve function.
• Postural awareness to reduce strain on your shoulder.
• Gradual return to normal activities as pain improves.

Your healthcare provider may recommend additional treatments such as biological therapies or, in some cases, surgical intervention, depending on the underlying cause and your individual circumstances.

Frequently asked questions

Q: Can shoulder stiffness go away on its own?
A: Some mild cases of shoulder stiffness caused by minor strain may improve with rest and gentle movement. However, if stiffness is progressive or associated with pain, professional assessment is advisable to identify the cause and prevent long-term problems.

Q: Is it safe to exercise with shoulder pain?
A: Gentle, guided movement is often beneficial, but high-impact exercise or activities that trigger sharp pain should be avoided. A physiotherapist or specialist can advise you on safe exercises tailored to your condition.
