Shoulder tip pain after keyhole cancer surgery | CION Cancer Clinics
Shoulder pain after keyhole surgery is common. The gas used to lift the tummy wall irritates a nerve under the ribs, and the brain feels it in the tip of the shoulder. It usually fades over a few days as the body absorbs the gas. This page explains why it happens, what eases it, and the signs that mean it is something else. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Why does your shoulder hurt after keyhole surgery?
The gas used to lift the tummy wall during keyhole surgery irritates a nerve under the ribs, and your brain feels that irritation in the tip of the shoulder. It is common, it is not a shoulder injury, and it usually settles within a few days as the body absorbs the leftover gas.
What the gas is for
In keyhole surgery, also called laparoscopic surgery, the surgeon works through small cuts using a camera. To make room to see and work, the tummy is gently filled with carbon dioxide gas. Most of it is let out at the end, but a little stays behind.
Why the pain turns up in the shoulder
The leftover gas rises and sits under the diaphragm, the dome-shaped breathing muscle under your ribs. The nerve that serves the diaphragm shares a pathway with nerves from the shoulder. So the brain reads the irritation as shoulder pain. Doctors call this referred pain.
What it feels like
Most people describe a deep ache or a sharp catch at the top of one or both shoulders. It is often worse when you sit up, stand or take a deep breath. Some people feel it at the base of the neck or under the ribs too.
Who it happens to
Which operations and which people get it more?
Shoulder tip pain can follow any operation where the tummy is filled with gas. Some situations make it more likely.
Operations inside the tummy
Keyhole operations on the bowel, stomach, liver, kidney, womb or ovaries all use gas. A diagnostic laparoscopy, where the surgeon only looks and takes samples, can cause it too.
Also includes
- Robot-assisted operations in the tummy
- Keyhole surgery to remove lymph nodes
Longer operations
The longer the tummy stays filled with gas, the more irritation there tends to be. Your surgeon can tell you roughly how long your operation took.
Head-down positions
Pelvic operations often tilt the table so the head is lower. Gas collects under the diaphragm, and some people also get a stiff neck and shoulders from the position itself.
Slim and younger people
Some studies suggest shoulder tip pain is reported more often by younger and slimmer patients, though the evidence is mixed. Anyone can get it.
Not sure whether this applies to you?
Ask an oncologistWhat helps
What can you do to ease shoulder tip pain?
Get up and walk
Gentle walking, as soon as the team allows, helps the body absorb the gas faster. Short walks often help more than lying still.
Change position
Some people find lying flat eases it, because gas moves away from the diaphragm. Others prefer sitting propped up. Try both and use whatever gives relief.
Breathe slowly and deeply
Deep breaths can catch at first, but slow breathing exercises help the lungs and the diaphragm settle. Hold a pillow over your tummy if the cuts pull.
Use gentle warmth
A warm towel on the shoulder can ease the ache. Avoid very hot bags on numb skin or near a painkiller patch, and ask the nurse first.
Take your painkillers as prescribed
Regular doses of the medicine you were given work better than waiting until the pain is bad. Do not add other tablets on your own.

One thing that cannot wait
Shoulder pain with sudden breathlessness, chest pain, a fast heartbeat, fainting, coughing up blood, or pain that keeps getting worse with fever and a swollen tummy is not ordinary gas pain. Go to the nearest emergency department straight away and say you have just had keyhole surgery. Do not wait for it to settle on its own.

On your discharge summary
What do the words about keyhole surgery mean?
- Laparoscopic
- Keyhole surgery on the tummy, done through small cuts with a camera and long thin instruments.
- Pneumoperitoneum
- Filling the tummy with gas during keyhole surgery, so the surgeon has room to see and work.
- Diaphragm
- The dome-shaped breathing muscle between the chest and the tummy. Leftover gas collects underneath it.
- Referred pain
- Pain felt in one part of the body when the cause is somewhere else, because the nerves share a pathway.
- Conversion to open
- When a keyhole operation had to be finished through a larger cut. Recovery and pain are then closer to open surgery.
Commonly believed
What do people fear shoulder pain after surgery means?
"Left shoulder pain means it is a heart attack."
After keyhole surgery, shoulder tip pain from gas is far more common than a heart problem. But heart pain can spread to the shoulder. If the pain comes with chest tightness, sweating or breathlessness, treat it as an emergency.
"They must have hurt my shoulder during the operation."
The shoulder itself is usually fine. The pain is referred from under the ribs. Stiffness from lying still on the table can add to it, and that eases with movement too.
"Keyhole surgery should mean no pain at all."
Keyhole surgery often means smaller wounds and less wound pain. You can still feel sore inside, and shoulder tip pain is part of that for many people.
"Resting completely will make the gas go faster."
Gentle movement usually helps more. Walking also lowers the chance of blood clots and chest infection.
Being straight with you
When might shoulder pain be something else?
This page cannot tell you why your own shoulder hurts. Gas is the usual reason after keyhole surgery, but it is not the only one. If the pain does not follow the usual pattern, ask your surgical team to check.
Pain that lasts or grows
Gas pain usually fades steadily over a few days. Shoulder pain that appears later, lasts much longer, or gets worse can come from blood or fluid collecting under the diaphragm, an infection, or a leak after bowel or stomach surgery. These need a doctor to examine you, and sometimes a scan.
Pain from the lungs
A blood clot in the lung can cause shoulder or chest pain, especially when breathing in. It often comes with breathlessness. This is an emergency.
If you already had shoulder problems
A frozen shoulder, arthritis or neck problems can flare after lying in one position. Tell the team about them before surgery, so they can pad and position you with care.
If you are unsure, call the number on your discharge summary. A quick call is better than a long wait.Questions we are asked
Common questions about shoulder pain after keyhole surgery
How long does shoulder pain last after laparoscopic surgery?
For most people it is worst in the first day or two and fades over a few days as the body absorbs the leftover gas. If it lasts longer, is getting worse, or comes with fever, breathlessness or a swollen tummy, call your surgical team rather than waiting it out.
Why is it only in my right shoulder?
Gas can collect more on one side, depending on your position during and after surgery and the shape of the organs under the diaphragm. Pain in one shoulder, both shoulders or moving between them can all be normal. The pattern over the next few days matters more than the side.
Do painkillers help shoulder tip pain?
Yes, the painkillers prescribed after surgery usually help, especially when taken regularly. Walking and changing position often help as much. Do not take extra tablets or buy anti-inflammatory painkillers from a shop, as some are not safe after surgery. Ask your team what to use.
Can peppermint water or fizzy drinks get the gas out?
The gas is inside the tummy space, not in the stomach or bowel, so burping and drinks do not release it. Warm drinks may still feel soothing. Fizzy drinks can add bloating. Check with your team before drinking anything if you have had bowel or stomach surgery.
Can the gas pain affect my breathing?
It can make deep breaths catch, so you may take shallow breaths without noticing. That can raise the chance of a chest infection, which is why breathing exercises help. Real breathlessness, especially if it is sudden, is not gas pain and needs emergency care.
Can I sleep on my side with this pain?
Usually yes, if the cuts allow. Many people find lying flat, or on the side that does not hurt, eases it. Use pillows to support your tummy and back. If you have drains or a stoma, ask the nurse which positions are safe.
Will I get shoulder pain every time I have keyhole surgery?
Not necessarily. It depends on the operation, how long it takes, how much gas stays behind and how your body responds. If it was very uncomfortable last time, tell the anaesthetist and surgeon before the next operation. They may be able to plan pain relief differently.
Can I travel home to my district with this pain?
Shoulder tip pain alone does not usually stop you going home once the team discharges you. Plan to stop and walk during a long journey. Carry your discharge summary, medicines and the team's number. Know where the nearest emergency department is at home.
