Axillary Web Syndrome (Cording)
Axillary Web Syndrome (AWS), more commonly known as cording, is characterised by the development of tight, rope-like cords beneath the skin. These cords typically extend from the axilla (armpit) down the inner upper arm but may also reach as far as the elbow, forearm, or wrist. In some cases, the cords can also appear across the chest wall or into the side of the trunk. The cords become more visible or palpable when the arm is lifted or stretched and can restrict movement and cause pain.
AWS most commonly occurs after breast cancer surgery (e.g. mastectomy, lumpectomy, reconstruction, sentinel lymph node biopsy, axillary lymph node dissection/clearance), radiation therapy, and occasionally after other surgeries (e.g. skin cancer excision) or trauma involving damage to lymphatic structures in the same body region.
What Causes Axillary Web Syndrome?
The exact cause of AWS is still being researched, but it is believed to involve:
- Injury to and inflammation of lymphatic vessels
- Thrombosis or scarring within lymphatic channels
- Fascial and connective tissue restriction
It is thought that the tissue damage caused by surgery and radiation therapy can lead to inflammation and the development of scar (connective) tissue in the armpit. In AWS, this connective tissue surrounds the lymph vessels and becomes fibrotic (hardened), which is what causes the cords to form.
When Does Axillary Web Syndrome Develop?
AWS typically develops within days to weeks after surgery, but it can also appear months or even years later. Delayed onset cording is more common than previously thought, and can be triggered by changes in activity levels, scar tissue tightening, or inflammation, which is why ongoing monitoring is essential.
Common Symptoms of Axillary Web Syndrome
Symptoms of AWS can range from mild to severe and may include:
- Visible or palpable cords under the skin
- Tightness or pulling sensations in the armpit and/or arm
- Pain or discomfort with movement
- Difficulty lifting the arm overhead
- Reduced shoulder range of motion
- Fear of movement due to pain
Many people describe the sensation as a “string pulling” or “rubber band tightening” when they try to reach or stretch the affected side.
Why Early Treatment Matters
With the right care and early intervention, AWS is highly treatable, and most people experience significant improvement in symptoms or full resolution.
1. Preventing Long-Term Movement Restrictions
Without treatment, cording can lead to:
- Ongoing tightness and pulling in the armpit
- Persistent shoulder stiffness
- Altered movement patterns
- Secondary neck, shoulder, or back pain
- Restriction in performing daily tasks
Early intervention helps restore normal movement before compensatory patterns develop.
2. Reducing Pain and Fear of Movement
Pain and tightness can cause people to limit their upper limb use, which can:
- Slow recovery after surgery
- Increase joint stiffness and muscle weakness
- Delay return to normal daily activities
Early, guided treatment helps reduce discomfort and rebuild confidence in movement.
3. Supporting Lymphatic Health
Because AWS involves lymphatic structures, untreated cording can place additional strain on the lymphatic system. Early management supports optimal lymphatic circulation and can help reduce future lymphatic complications such as the development of lymphoedema.
How is Axillary Web Syndrome Diagnosed?
Diagnosis is usually made through:
- A detailed clinical history
- Clinical observation and palpation
- Functional and range of motion assessment
Imaging is rarely needed. A trained cancer rehabilitation and lymphoedema therapist can typically identify AWS during assessment.
Treatment Options for Axillary Web Syndrome
1. Manual Therapy
Specialised manual therapy techniques for AWS include:
- Gentle cord stretching and release
- Myofascial techniques
- Scar tissue mobilisation
- Manual lymphatic drainage for secondary swelling
These techniques are applied carefully and progressively, avoiding excessive force.
2. Therapeutic Exercise
Targeted exercises are essential for recovery and often include:
- Shoulder range of motion and strengthening exercises
- Gradual stretching of the affected tissues
- Postural retraining exercises
- Functional movement retraining
Exercises are introduced gradually and are tailored to individual comfort and functional capacity.
3. Low-Level Laser Therapy
Low-level laser therapy (LLLT), also called photobiomodulation, can be used as a supportive treatment for cording to help reduce pain, inflammation, and tissue tightness. By delivering low-intensity light to the affected areas, LLLT can promote cellular healing, improve lymphatic flow, and soften the fibrotic cords, which can reduce pain and tightness, and enhance shoulder mobility and comfort. It is typically used alongside other treatment interventions rather than as a stand-alone treatment. Read more about the LLLT we provide in clinic here.
4. Education and Self-Management
Education is a key component of treatment and often includes:
- Understanding what cording is (and what it isn’t)
- Guidance on safe movement
- Advice on pacing and gradual return to activity
- Reassurance that movement is safe and beneficial
- Individually prescribed home exercise program
5. Pain and Inflammation Management
For self-management of symptoms:
- Heat or cold therapy (as appropriate)
- Gentle self-massage techniques
- Temporary activity modification
Does Axillary Web Syndrome Go Away?
In many cases, AWS resolves completely, especially with early and appropriate treatment. Some people experience improvement over weeks, while others may take several months depending on consistency of therapy, severity, surgical history, and individual healing capacity.
Occasionally, mild cording may recur during periods of increased activity or tissue stress, but this is usually identified early through ongoing monitoring and managed effectively with early intervention.
When to Seek Help
You should seek assessment for cording if you notice:
- Tight cords under the skin after surgery and/or radiation therapy
- Pain or pulling in the armpit or arm with overhead movement
- Difficulty lifting your arm or performing normal daily tasks
Final Thoughts
Axillary web syndrome can be alarming, especially when it appears unexpectedly after surgery. However, it is a well-recognised and treatable condition. With the right support, education, and therapy, most people regain comfortable, confident movement and return to normal activities.
If you are experiencing symptoms of cording, early assessment by a trained cancer rehabilitation and lymphoedema professional can make a significant difference.
You don’t have to push through pain—help is available, and recovery is possible.
