LYMPH•LOGISCH · Understand your symptoms
When your arm feels tight: understanding cording.
Does a cord feel tight from the armpit into the arm when you reach up? This may be axillary web syndrome. Focused assessment and gradual movement are important.
What might feel familiar?
Washing your hair, dressing or lifting your arm causes pulling or pain. A tight cord may be visible or palpable beneath the skin. Cording, also called axillary web syndrome, can develop after lymph node surgery, for example after removal of lymph nodes in the armpit. It can also occur after a sentinel lymph node biopsy and is not exclusive to breast cancer. [3] It differs from lymphoedema, although both can occur together.
What causes it?
The exact mechanism is not fully understood. Changes in superficial lymphatic vessels and surrounding tissue have been proposed. The cord becomes particularly tight during movements that lengthen the affected area. Avoiding these movements can further limit shoulder mobility.
Why use tailored exercises?
I use targeted manual techniques and adapted movements to address restricted tissue mobility. The aim is to ease tension and improve shoulder and arm movement. Treatment intensity and your exercise programme are adapted to your symptoms and stage of healing.
Does the cord have to be clearly visible?
Not always. Some cords become visible only when the arm is raised and the elbow straightened. Others are mainly felt as pulling in the armpit, upper arm or towards the forearm. Raising the arm sideways or forwards can be affected. Symptoms, physical findings and the surgical history matter together. An ordinary-looking photograph therefore cannot rule out cording. [3]
How does cording differ from scar tightness and lymphoedema?
A scar may pull locally, while a cord often creates tension along a longer line. Lymphoedema more typically involves swelling, heaviness or tissue changes. These problems can coexist after surgery and influence each other. The shoulder joint and muscles are also assessed. Treatment therefore addresses the structures that actually limit movement, rather than concentrating only on the visible cord. [4]
What does it mean when something gives way during treatment?
Sometimes tension changes suddenly and movement immediately feels freer. You may notice a release or a quiet popping sensation. That experience alone cannot identify exactly which structure changed. Relief can also develop quietly and gradually. Reduced pain, improved movement and a good tissue response are what matter. Further treatment remains carefully dosed and adapted to healing and examination findings. [4]
How can I practise without constantly fighting the pulling?
Your movement and stretching programme is adapted to difficulties such as dressing, washing your hair or lifting the arm forwards or sideways. Exercises progress gradually rather than pushing harder into pain. Report new swelling, increasing pain or a lasting deterioration. If the cord becomes less visible but shoulder movement remains restricted, reassessment is still worthwhile. [1], [4]
Research in context
What do the studies show?
The exercise and drainage trial specifically studied cording.
Torres-Lacomba and colleagues studied 96 women with axillary web syndrome in 2022. Tailored arm exercises and drainage outperformed standard exercises immediately and at three months, but not at six months. This was a combined programme rather than drainage alone. [1]
A newer trial of stretching and manual treatment.
A 2025 randomised trial involving 46 patients reported better pain, movement and recovery with stretching, manual techniques and scar treatment. The single-centre findings are encouraging, but cannot establish which technique caused the benefit or is essential for everyone. [4]
Why treatment rankings are not universal instructions.
The 2026 network meta-analysis combined 14 trials with 1,007 participants. Several combinations showed possible benefits. Different programmes, few direct comparisons and model-dependent findings limit certainty. A statistical ranking does not mean every additional technique should be used. [2]
Finding confidence in movement again.
With cording, I want to assess shoulder and arm movement as well as the cord itself. We look at where you feel pulling, what limits you and how the tissue responds to treatment. Your movement and stretching programme should help you move more freely, step by step.
