The short answer
How do you tell if pain after surgery is not normal?
Normal pain after surgery is worst in the first few days and then eases a little each day. Pain that gets worse after it was easing, pain that painkillers no longer touch, or pain that comes with fever, vomiting, breathlessness or a swollen leg is not normal and needs a doctor.
What expected pain looks like
Soreness around the cut, worse when you move, cough or get out of bed. Aching from drains and tubes. Stiff muscles from lying still. It responds to the painkillers you were given, and each day you can do a little more than the day before.
The pattern matters more than the score
A high pain score on the first day can be normal. A lower score that starts climbing again several days later is more worrying. Doctors look at the direction of travel: is it settling, flat, or getting worse?
Why this matters at home
Many people go home before the wound has fully healed. Problems such as infection, a leak inside, or a blood clot can appear after discharge. Pain is often the first sign, so it is worth taking a change seriously.
!
One thing that cannot wait
Go to the nearest emergency department straight away if pain comes with sudden breathlessness, chest pain, fainting, a fast heartbeat, vomiting with a swollen hard stomach, high fever with shivering, or confusion. Take your discharge summary with you and say you have just had surgery. Do not take extra painkillers and wait to see if it settles.

Which kinds of pain can point to a problem?
None of these proves something is wrong. Each one is a reason to call your surgical team the same day.
A wound that is getting worse
Pain increasing around the cut, with redness spreading, heat, swelling, a bad smell, or pus or cloudy fluid leaking out. This can mean infection.
Pain deep in the stomach
Pain that spreads across the whole tummy, gets steadily worse, and comes with fever, vomiting or a swollen stomach. After bowel or stomach surgery, this can mean a leak where the gut was joined.
A painful, swollen leg
Pain in one calf or thigh, with swelling, warmth or redness. This can mean a blood clot in a deep vein. It needs checking the same day.
Go to emergency if also
- Sudden breathlessness
- Chest pain when breathing in
Pain nothing seems to touch
Pain that is far worse than the day before, or no longer eases with the medicines that worked earlier. This alone is reason enough to call.
The usual course
What does ordinary recovery pain usually look like over time?
-
The first few days
Pain is at its strongest. It is controlled with a drip, a pump, an epidural or strong tablets. Nurses ask you to score it many times a day. Moving, coughing and deep breaths hurt, but you can still do them with support.
-
Towards going home
Pain has usually moved to tablets. You can walk to the toilet and sleep for longer stretches. The wound is tender to touch but not getting redder or more swollen.
-
The first weeks at home
Soreness eases steadily, though you may have a bad day after doing too much. Tiredness is common. You need less painkiller as the days go on.
-
After the wound has healed
Most pain has gone. Some numbness, tightness or odd sensations around the scar can last much longer. Pain that stays or returns months later is worth raising at follow-up.

Commonly believed
What stops families calling the doctor in time?
"Surgery is supposed to hurt, so we should not complain."
Some pain is expected, but a change in the pattern is information the team needs. Calling about a worry that turns out to be nothing is far better than waiting on a problem that grows.
"We will wait for the follow-up appointment."
The follow-up date was set for a normal recovery. If something has changed, call the surgical team now. They would rather see you early.
"More painkillers will sort it out."
Taking extra doses can hide a fever or an infection while it gets worse, and it risks overdose. Do not change the dose on your own. Call instead.
"She is older, so she will just feel more pain."
Older people sometimes show a problem as confusion, drowsiness or not eating rather than as pain. A sudden change in how an older relative is behaving after surgery is a reason to call, even if they say the pain is fine.
Being straight with you
What should you tell the doctor, and what can this page not tell you?
This page cannot tell you whether your own pain is normal. The operation you had, the joins made inside, and your other conditions all change what counts as expected. Only someone who can examine you, and sometimes order a blood test or scan, can answer that.
How to describe the pain on the phone
Say where it is, when it started, and whether it is getting better or worse. Say whether it is sharp, burning, cramping or aching, and what makes it worse. Mention any fever, vomiting, stool or urine changes, wound changes, or a swollen leg. Have your discharge summary and medicine list in front of you.
Pain that has other causes
Not all pain after surgery comes from the operation site. Shoulder tip pain after keyhole surgery, a stiff back from the operating table, constipation from painkillers, and burning nerve pain around a scar are all common. They still deserve a mention to the team, because the treatment is different for each.
If you are unsure whether to call, call. Keep the surgical team's number and the nearest emergency department written down at home.Questions we are asked
Common questions about abnormal pain after surgery
Is it normal for pain to get worse a few days after surgery?
A brief rise after doing more, or when a pain pump or epidural is stopped, can be normal. Pain that keeps getting worse day after day, or comes with fever, vomiting, redness at the wound or a swollen leg, is not. Call your surgical team the same day if you are unsure.
How do I know if my wound is infected?
Signs include increasing pain around the cut, redness that spreads, warmth, swelling, pus or cloudy fluid, a bad smell, the wound edges opening, or fever. A little clear or pinkish fluid early on can be normal. Take a photo each day so you can show the team how it has changed.
Can I just take more of my painkillers?
No. Taking more than prescribed can cause overdose, stomach bleeding or liver damage, depending on the medicine. It can also hide a warning sign. If the prescribed dose is not controlling the pain, that itself is something to report. Call the team and let them decide.
What does pain in the calf after surgery mean?
It can be a strained muscle from lying still, but it can also be a blood clot in a deep vein. A clot is more likely if the calf is swollen, warm or red on one side. Get it checked the same day, and go to emergency if you also feel breathless or have chest pain.
I had keyhole surgery. Why does my shoulder hurt?
The gas used to lift the tummy wall during keyhole surgery can irritate a nerve, and the pain is felt in the shoulder. It is common and usually settles within days. Chest pain, breathlessness or shoulder pain that keeps getting worse is different and needs a same-day check.
Who should I call at night or on a holiday?
Use the number on your discharge summary first. If you cannot reach the team and the symptoms feel serious, go to the nearest emergency department. Take the discharge summary, your medicine list and any recent reports. Tell them clearly what operation you had and when.
My father says he is fine but he seems confused. Should we worry?
Yes. In older people, new confusion, drowsiness or refusing food can be the first sign of infection, dehydration or a medicine side effect, even with little pain. Call the surgical team the same day, and go to emergency if he is very hard to wake or breathing badly.
Could the pain mean the cancer has come back?
In the weeks after surgery, pain is far more likely to come from healing or a complication. Pain that appears or returns months later, in a new place, should be checked, but many causes are harmless. This page cannot tell you which it is. Raise it with your doctor rather than waiting.
