Cording after surgery: stretching and physiotherapy

Cording, also called axillary web syndrome, is a common condition after breast cancer surgery that removes or samples lymph nodes from the armpit. It causes tight, rope-like bands under the skin that usually run from the armpit down the inner arm, sometimes as far as the wrist or thumb. The cords are thought to be hardened lymph vessels and surrounding tissue. They make it painful to raise or straighten the arm, and they often appear in the first few weeks after surgery. Cording is not dangerous, and for most people it improves over weeks to a few months. Gentle stretching, regular movement and physiotherapy help it settle faster and prevent the shoulder becoming stiff.

What it feels like

A pulling or tight sensation when reaching up or straightening the elbow, a visible or felt cord under the skin, and discomfort in the armpit or inner arm.

What helps most

Daily gentle stretching within comfort, keeping the arm moving, massage techniques taught by a physiotherapist, and simple pain relief if needed.

When to seek advice

Seek help if pain is severe, the arm becomes red, hot or swollen, you have a fever, or movement does not improve over several weeks.

Cording can be surprisingly painful and frustrating, especially when you are trying to recover from surgery and get back to daily tasks. The reassuring news is that it usually improves, often within weeks to a few months.

Cords can sometimes snap

During stretching or daily movement, a cord may release with a small pop or snapping feeling. This is usually harmless and often brings relief.

Stretching should not be forced

Gentle, regular stretching works better than pushing through severe pain, which can irritate the tissues.

It can return

Cording sometimes reappears months later, for example after radiation or increased activity. The same approach usually helps again.

What this page cannot tell you

It cannot diagnose cording. Ask your team or physiotherapist to examine your arm.

Cording can make reaching, dressing and household work difficult for a while. A few adjustments help.

Dressing

Front-opening tops and kurtas are easier than pulling clothes over your head.

Reaching

Keep often-used items at waist or shoulder height, and ask for help with high shelves.

Keep moving

Use the arm for light daily activities rather than resting it completely, which can make stiffness worse.

Before radiation

Good shoulder movement is needed for positioning during radiation. Tell your team if cording is limiting your arm.

Radiation often follows breast surgery, and cording can affect it in practical ways.

Arm position during treatment

Radiation usually requires lying with the arm raised above the head. Tight cords can make this position difficult or painful to hold.

Preparing before radiation

Starting stretching and physiotherapy early helps you reach the position needed. Tell your team if you are struggling.

After radiation

Keep stretching during and after treatment, as radiation can tighten tissues and cords can sometimes return.
