— and Why Does My Arm Feel Tight or Pulling?

Start here if this sounds like you…

  • Your arm feels tight when you lift it
  • There’s a pulling feeling under your arm or into your chest
  • You’ve noticed a line or cord appear when you stretch
  • Your movement hasn’t quite come back after surgery
  • Or something just doesn’t feel quite right… but you’re not sure why

Let’s start simply

You might hear it called cording… or axillary web syndrome.

But most people don’t use those words.

They say things like:

“It feels like something is pulling under my arm”
“There’s a tight line when I reach up”
“I can’t quite move the same way anymore”

And once you notice it, it’s hard to ignore.

What is cording?

Cording is a tight, rope-like band that can form under the skin, usually:

  • from the armpit (axilla)
  • down the inner arm
  • sometimes extending into the chest wall

You might only see it when you stretch.

Or you might not see it at all — just feel the restriction.

 

Often you only see it when the arm is lifted — but what’s happening underneath matters more than what you can see.

How common is it?

This surprises a lot of people.

Cording is not rare:

  • Around 20–70% of people experience it after breast cancer surgery
  • It is more common when lymph nodes are removed
  • It often appears within the first few weeks, but can show up later

Research suggests cording is linked to changes in lymphatic vessels and surrounding connective tissue following surgery.

And yet…

– many people are never warned about it beforehand

What’s actually happening under the surface?

This is the part that helps it make sense.

Cording isn’t just a surface line.

It’s usually a combination of:

  • Lymphatic disruption (from surgery)
  • Scar tissue forming as part of healing
  • Fascial layers becoming less mobile
  • Inflammation increasing sensitivity and tension

So instead of tissues gliding easily…

– things can start to feel a bit “stuck” or under tension

Healthy tissue layers glide. When things feel tight, those layers aren’t moving as freely.

Why it feels tight (and sometimes limiting)

Cording doesn’t just sit quietly in the background.

It can:

  • pull when you lift your arm
  • limit how far you can reach
  • create a feeling of tension or discomfort
  • affect how confident you feel using your arm

It’s often more noticeable when you stretch — because that’s when the system is under load.

Is it linked to swelling or lymphoedema?

They’re not the same thing.

But they do share a similar environment.

  • Both relate to how the lymphatic system is coping
  • Both can follow surgery or lymph node removal

Some studies suggest an association between cording and lymphoedema, although they are considered separate conditions.

So rather than separating them completely, it can help to think:

• this is a system that may need support

When people come to see me about this…

Most people don’t come in saying:

“I have cording.”

They say:

  • “My arm feels tight when I reach”
  • “There’s a pulling under my arm”
  • “Something just doesn’t feel right since surgery”

Sometimes there’s a visible cord.

Sometimes there isn’t.

What I’m looking at is:

  • how the tissues are moving
  • where things feel restricted
  • how the lymphatic system is coping
  • how confident someone feels using their arm

What actually helps?

This is where we move away from worry… and into support.

Gentle, supported movement

Not forcing. Not pushing through discomfort.

Just gradually restoring:

  • movement
  • confidence
  • tissue glide

 – cancer rehab sessions

Manual Lymphatic Drainage (MLD)

Helps to:

  • support lymphatic flow
  • reduce pressure in the tissues
  • create a better environment for healing

Research supports that combining movement-based rehab and manual therapy can improve pain and function in people with cording.

Scar therapy

Scar tissue is part of healing — but it can influence:

  • how tissues move
  • how the arm feels
  • how comfortable stretching is

Gentle scar therapy can help restore movement between layers

Scar therapy

Rhythmic, supported movement (like WALX)

This is often overlooked — but really important.

  • arm swing supports lymphatic flow
  • rotation improves tissue movement
  • rhythm supports the nervous system

• it’s not about fitness
• it’s about flow and confidence

WALX / rehab walking sessions

Movement isn’t just exercise — it’s how the body restores flow and confidence.

Time… with the right support

Cording can improve on its own.

But without support:

  • movement patterns can change
  • confidence can drop
  • compensation can build

Early support can make a real difference to how easily movement comes back.

This is something I see a lot.

And people often say:

“I thought it was just tightness.”

And yes… it is.

But it’s also your body trying to reorganise after something significant.

With the right support:

  • tissues can soften
  • movement can return
  • and things can start to feel more like you again

If this sounds familiar…

I work with people at different stages of recovery —
whether you’re newly post-surgery or months (or years) down the line and something still doesn’t feel right.

Supporting:

  • cording and tightness
  • swelling and lymphatic concerns
  • scar-related restriction
  • rebuilding movement and confidence

Support doesn’t need to be complicated — just the right approach at the right time.
