Shoulder Pain: Causes, Symptoms and Treatment Options

Shoulder Pain, Written and medically reviewed by Dr Dinesh Sirisena · Consultant in Sports, Exercise & Musculoskeletal Medicine · Triaxis Sports & Joint Clinic

In short: Shoulder pain is very common and usually improves without surgery. Because the shoulder is so mobile, many different structures — the tendons, the joint capsule, the labrum or the joint itself — can cause similar symptoms, so identifying the source matters. Most causes respond well to a guided programme and, where helpful, minimally invasive image-guided treatment.

Key points at a glance

• The shoulder’s large range of movement makes it prone to several treatable conditions.
• Most shoulder pain improves without surgery.
• Where the pain sits often hints at the cause (see the table below).
• Sports ultrasound can assess the tendons and joint during movement and guide treatment.
• A few warning signs need urgent attention (below).

When shoulder or arm pain is an emergency

Seek emergency care if shoulder, arm or upper-body pain comes on with chest tightness or pressure, breathlessness, sweating, nausea, or pain spreading to the jaw or down the arm — these can be signs of a heart problem rather than a muscle or joint issue. Also seek prompt care after a significant injury with deformity, or if you cannot move the arm at all.

Why does my shoulder hurt?

Shoulder pain develops when the tendons, joint capsule, labrum or joint surfaces become overloaded, irritated or injured. Sometimes it follows a specific event; often it builds gradually without a clear injury.

• Repetitive overhead activity
• Sport
• Heavy lifting
• Falls
• Workplace activities
• Age-related changes
• Previous shoulder injuries

What are the common causes of shoulder pain?

A handful of common, treatable conditions account for most shoulder pain. Identifying which one you have guides the right treatment.

• Rotator cuff conditions — tendinopathy or tears
• Frozen shoulder (adhesive capsulitis)
• Subacromial pain, sometimes called “impingement”
• Biceps tendinopathy
• Labral injury
• Shoulder instability
• Shoulder arthritis

Each of these is covered in more detail on its own page.

What does shoulder pain feel like, and where is it felt?

Shoulder pain can be a dull ache, sharp pain on certain movements, or increasing stiffness. Where it sits often points to the structures involved.

Where the pain is	What it may involve
Front of the shoulder	Biceps tendon or the shoulder joint
Outer shoulder	Rotator cuff or subacromial pain
Top of the shoulder	The AC (acromioclavicular) joint
Back of the shoulder	Muscular or throwing-related causes
Into the upper arm	Referred from the shoulder (not the elbow)

Pain that travels below the elbow, or comes with numbness or tingling, may point to the neck or a nerve rather than the shoulder itself.

Do I need a scan for shoulder pain?

Not always. Shoulder pain is usually assessed from your symptoms and examination, with imaging used selectively. Sports ultrasound is particularly useful for looking at the tendons and bursa during movement, and can also guide treatment.

MRI may be considered when more detail about deeper structures is needed.

What are the best treatments for shoulder pain?

Most shoulder pain is treated without surgery, using a complete programme of guided rehabilitation and, where helpful, minimally invasive image-guided injections. The right plan depends on the specific diagnosis.

• Activity modification
• A guided mobility and strengthening programme
• Education about shoulder movement
• Image-guided corticosteroid or PRP injections where appropriate
• Shockwave therapy or barbotage (ultrasound-guided needling) for calcific tendinopathy where appropriate
• Percutaneous ultrasonic tenotomy (Tenex) for selected tendon problems, including calcific rotator cuff tendinopathy
• Nerve hydrodissection where a nerve is compressed around the shoulder or neck
• Hydrodilatation for frozen shoulder
• Sports ultrasound assessment to confirm the diagnosis and guide treatment

Do I need surgery for shoulder pain?

Surgery is not needed for most shoulder pain. The majority of conditions improve with non-surgical care, and surgery is reserved for specific problems — such as certain traumatic tears or recurrent instability — rather than shoulder pain in general.

Can shoulder pain improve over time, and how long does it take?

Many shoulder conditions improve with the right programme, although the timeline depends on the diagnosis — some settle within weeks, while others, such as frozen shoulder, take longer.

When should I see a doctor for shoulder pain?

Seek assessment if shoulder pain lasts several weeks, limits movement, disturbs sleep, or follows an injury. Seek urgent care for the warning signs above.

• Pain lasting several weeks
• Increasingly restricted movement
• Pain interfering with work or sport
• Disturbed sleep
• Developing weakness
• Pain following a fall or injury
• No improvement with self-management

Frequently asked questions

Why does my shoulder hurt at night?

Night pain is common with rotator cuff problems and frozen shoulder; effective treatment usually improves sleep as the shoulder settles.

Can shoulder pain come from the neck?

Yes. Pain spreading below the elbow, or with tingling, may actually originate in the neck.

Will shoulder pain go away on its own?

Many cases improve, but persistent or worsening pain is worth assessing so the right treatment can start.

Does shoulder pain mean a rotator cuff tear?

Not necessarily. Several conditions cause similar pain, which is why assessment matters.
