Collarbone pain is often thought to be caused by posture or muscle strain, but when it lasts more than a few days, it may indicate a deeper shoulder condition. The collarbone (clavicle) supports the shoulder joint, allowing you to lift and move your arm. When discomfort develops, it may arise from muscle tension, joint inflammation, nerve irritation, or even a small fracture.
Whether you are working long hours at a desk, training actively, or recovering from a fall, recognising when pain needs medical attention helps prevent further injury and supports recovery.
Understanding Collarbone and Shoulder Pain
The collarbone connects the chest bone to the shoulder blade, helping to stabilise your shoulder during daily activities. Pain can occur due to injury, inflammation, or nerve compression near the shoulder region.
Common Causes of Collarbone or Shoulder Pain
- Muscle strain or overuse – Common among those with poor posture or repetitive lifting.
- Joint inflammation or sprain – Especially at the acromioclavicular (AC) joint.
- Fracture or trauma – Often due to a fall or sports-related impact.
- Shoulder Arthritis – Gradual wear of the shoulder or collarbone joints leading to stiffness.
- Referred pain – Nerve irritation from the neck or upper back radiating to the collarbone.
When Collarbone Pain Is More Than a Muscle Strain
Sometimes, collarbone pain suggests an underlying joint or nerve issue. Recognising the warning signs helps you seek professional care early.
Warning Signs That Need Medical Attention
- Persistent pain after an injury or fall
- Visible bump or deformity near the shoulder
- Pain that worsens with movement or deep breathing
- Numbness or tingling down the arm
- Swelling, warmth, or bruising at the collarbone
- Fever or fatigue accompanying pain
Other Conditions That Mimic a Simple Strain
Not all shoulder pain is due to muscle overuse. The following conditions can appear similar but may require different management approaches.
Shoulder Fracture or Dislocation
A broken or dislocated shoulder or collarbone often causes sharp pain and swelling immediately after trauma.
You may notice:
- A visible bump or sagging shoulder
- Bruising or grinding sounds with movement
- Pain that worsens when lying on the affected side
Even small fractures can result in long-term stiffness if left untreated. X-ray confirmation allows your doctor to plan appropriate stabilisation and rehabilitation.
AC (Acromioclavicular) Joint Arthritis or Sprain
The AC joint links the collarbone to the shoulder blade. Repetitive overhead activity or carrying heavy loads can inflame this area.
Common signs include:
- Pain on top of the shoulder near the collarbone
- Clicking or popping during movement
- Discomfort when lifting the arm across or above the body
Thoracic Outlet Syndrome (TOS)
TOS develops when nerves or blood vessels between the collarbone and first rib are compressed. It can mimic shoulder or neck pain.
Possible symptoms:
- Aching around the collarbone and upper shoulder
- Numbness or tingling down the arm
- Arm fatigue or weakness after activity
- Colour or temperature changes in the hand
Diagnosis may involve imaging or nerve studies, and treatment can include posture correction or minimally invasive nerve-release procedures.
Referred Pain from the Neck or Shoulder Joint
Neck and upper shoulder conditions such as cervical slipped disc, rotator cuff tendonitis, or facet joint irritation can cause pain that radiates toward the collarbone.
Indicators include:
- Stiffness in the neck or shoulder blade
- Pain travelling down the arm
- Tingling or weakness in the hand or fingers
At Singapore Paincare, the Painostic® treatment methodology helps identify whether pain originates from the shoulder, neck, or nerve pathways to guide suitable treatment.
How Shoulder and Collarbone Pain Are Diagnosed in Singapore
At Singapore Paincare, every assessment follows a structured process based on the Painostic® framework to determine the real pain source.
1. Clinical Evaluation
- Review of your symptoms and activity patterns
- Assessment of shoulder alignment and range of motion
- Diagnosis – muscle, joint, or nerve involvement
2. Imaging and Diagnostic Tests
- X-ray: Detects fractures or dislocations
- Ultrasound: Identifies tendon inflammation or joint fluid
- MRI: Evaluates soft tissue or nerve compression
- Nerve studies: Assess thoracic outlet or compression-related conditions
3. Painostic® Treatment methodology
The Painostic® system helps distinguish structural (joint or tendon) from functional (muscle or nerve) pain. This structured approach supports accurate diagnosis and guides appropriate, minimally invasive treatment plans.
Treatment Options for Collarbone Pain
Conservative Treatments
- Rest and temporary activity modification
- Ice application to ease swelling
- Doctor-advised medication for pain relief
- Shoulder physiotherapy for strengthening and posture correction
Minimally Invasive Treatments at Singapore Paincare
For persistent pain, targeted procedures can help manage symptoms effectively without open surgery:
- Coreflex specialised injections – Places anti-inflammatory medication precisely into affected shoulder joints.
- Nerve block therapy – Helps interrupt pain signals to allow rehabilitation.
- Platelet-Rich Plasma (PRP) therapy – Uses your own platelets to support tissue healing.
These are outpatient procedures performed with accuracy and safety, requiring no to little downtime.
When Surgery May Be Needed
Surgery may be considered for severe fractures or joint separations that do not respond to conservative or minimally invasive options. Singapore Paincare collaborates with orthopaedic partners to ensure coordinated care when required.
Living with and Preventing Shoulder Pain
Daily Prevention Tips
- Maintain upright posture while working or studying
- Strengthen upper back and shoulder stabilising muscles
- Take regular breaks from prolonged computer use
- Warm up before sports or exercise
Sleeping and Lifestyle Habits
- Sleep on your back or non-painful side with adequate pillow support
- Avoid lying directly on the affected shoulder
- Adjust chair and screen height to reduce strain

FAQs About Collarbone Pain in Singapore
Can sleeping on one side cause collarbone pain?
Yes. Prolonged pressure on one side can irritate the AC joint or shoulder muscles. Alternate sides and use a supportive pillow.
How long does a collarbone strain take to recover?
Mild strains usually improve within one to two weeks. Persistent pain may need physiotherapy or injection therapy.
Is collarbone pain related to heart problems?
Collarbone pain is usually caused by muscle strain, injury, or arthritis. Rarely, it can be related to heart problems, especially if accompanied by chest pain, shortness of breath, or jaw/arm pain. Seek immediate medical attention if these symptoms occur.
