For the first three weeks at home after an operation · 13 minutes
You were sent home with a leaflet saying some pain, some redness and some swelling are normal — and no way at all to tell which of yours is the one that matters.
Almost everything that goes wrong after an operation announces itself as a change in something that was already there. The pain was expected, so more pain reads as expected. The wound was red, so redder reads as red. That is why the useful work is not deciding whether today is bad: it is writing down, now, while nothing is wrong, exactly what would have to change before you ring — and taking the two or three measurements that make those changes visible. A line drawn round the redness with a pen and the time written next to it turns an argument with yourself at two in the morning into a comparison anybody can make in four seconds.
Change, not levelis what almost every complication looks like
Measure it nowwhile it is normal, so a change is visible later
Decide in advancea trigger set today is worth more than a judgement at 2am
Nobody rings because they cannot tell whether it counts as worse. Draw round the redness, write the time, note which painkiller got you through the afternoon, and take your temperature once while you feel fine. Those three things do most of the work of this whole page.
Your triggers, and what to measure now
Mark what you had done, how long ago, what came home with you and anything that raises the stakes. The tool writes out the triggers — if this changes to that, do this — and the small set of measurements to take in the next ten minutes so that each trigger is something you can actually check. Nothing is saved and nothing leaves the page.
If any of this is happening now — you cannot get your breath, chest pain, a wound that has opened or is bleeding heavily, vomiting everything for more than a few hours, no urine for eight hours with pain, confusion in an older person, or you simply feel profoundly unwell — do not wait for a trigger to fire. Ring the emergency number or the number the hospital gave you. Emergency number in Europe: 112.
What sort of operation was it?
How long ago?
Count from the day of the operation itself, and remember that the day you came home is not day one if you stayed in.
What came home with you?
Anything that raises the stakes?
These do not make a complication likely. They make it worth setting the trigger tighter and ringing earlier.
Is any of this happening right now?
What is expected, and what expected does not mean
Pain that eases day on day is the normal shape. It is usually worst on the second day rather than the first, because the anaesthetic and the strong painkillers given in theatre are still working on the first. A day of feeling worse after a day of feeling better is the pattern worth noticing.
A wound is expected to be pink at its edges, a little swollen, and sore to touch. Warm is normal. Hot, spreading, and increasingly painful after day three is not.
Feeling wiped out for far longer than anyone told you is normal. A general anaesthetic and a healing wound take weeks of energy, and being exhausted at three weeks is not a complication. Being suddenly exhausted after having been fine is different.
Bruising travels downwards and turns yellow-green. That is gravity and old blood, not infection, and it can appear a surprising distance from the wound.
A slightly raised temperature in the first day or two is common and often comes from shallow breathing rather than infection — which is why you are told to take deep breaths and cough. A fever that starts on day four or five is a different animal.
“Expected” describes a range, not your particular Tuesday. The purpose of knowing the normal shape is not to talk yourself out of ringing. It is so that when your own pattern breaks, you notice it early.
The wound, and the pen line
Draw round the redness with a pen and write the time beside it. This is the single most useful thing on this page. Spreading redness is the sign that matters and it is almost impossible to judge from memory; against a pen line it takes four seconds.
Infection usually arrives between day three and day ten, not on the first day. The pattern is redness that is spreading rather than fading, pain that is increasing rather than easing, heat, and often a fever or just feeling generally unwell.
Discharge changes meaning with its character. A little clear or blood-stained ooze in the first days is ordinary. Thick, cloudy, yellow-green or foul-smelling discharge is not, and neither is a wound that suddenly leaks a lot of fluid after being dry.
A wound that opens is a same-day problem, whatever it looks like. If deeper tissue is visible, cover it with a clean dressing, do not push anything back in, do not eat or drink until you have spoken to somebody, and ring the surgical team or the emergency number.
Stitches and staples that pull slightly are normal; skin glue peeling at the edges after a week is normal. A gap opening along the line is not.
Take a photograph in daylight on day two. Not for anybody else — for you, and for whoever you eventually show it to. Comparing two photographs is easier than describing a colour.
The complication that is quiet until it is not
An operation, an anaesthetic and a few days of not moving are the three things that most raise the risk of a clot in a leg vein, and of that clot travelling to a lung. It is the complication people are least warned about and the one where hours matter most.
Compare your two calves at the same point. Pain, swelling, warmth or redness in one calf — particularly a calf that is visibly bigger than the other — is a same-day question, not something to sleep on.
Breathlessness or chest pain that is new, especially with the calf, is an emergency-number call and not a phone call to the ward. It can happen in somebody who felt well an hour earlier.
Move early, move often, and drink. Getting up and walking about the house every hour while you are awake is not enthusiasm, it is treatment, and it does more against clots and chest infections than anything else you will be asked to do.
If you were given injections, stockings or tablets to prevent clots, finish the course. They are prescribed for the weeks after surgery precisely because the risk does not stop at the hospital door, and stopping early because you feel well is the commonest reason they fail.
A long journey in the first weeks needs planning, including flights. Ask before you book rather than after.
Pain that is failing, and pain that is a signal
Note what got you through today. Which painkiller, how many, and whether you needed them earlier than allowed. That note is the measurement; “a bit worse” is not.
Take the regular painkillers regularly for the first days rather than waiting for pain. Chasing pain that has already arrived needs more medicine for less effect, and pain that is not controlled keeps you still, which is how the clot and the chest infection get their chance.
Pain that needs more medicine each day rather than less is a signal, not a dosing problem. So is pain that changes character — from sore to gripping, from local to spreading, from bearable when still to bad all the time.
If you were given strong painkillers, assume constipation and act first. Opioids stop the bowel; a laxative from day one is standard practice and much easier than the alternative. Straining is also the last thing a fresh abdominal wound needs.
Do not add over-the-counter painkillers without checking what is already in them. The same drug appears under several names, and paracetamol overdose from combination products is a real and quiet way for this to go badly.
Pain relief that is genuinely not working is a reason to ring in normal hours, not to endure it until the review appointment. It is an ordinary call and it is usually solvable.
The parts nobody wants to ring about
Not passing urine is a same-day problem, not an embarrassment. After an operation, particularly with a spinal anaesthetic or anything near the pelvis, the bladder can stop emptying. Eight hours with none, or a swollen lower belly with an urge and nothing coming, needs help today.
Bowels that have not moved for several days after abdominal surgery deserve a phone call, especially with a swollen belly, no wind passing, or vomiting. Say all three symptoms rather than one.
Vomiting that continues past the first day, or that starts later, is not just the anaesthetic. Keeping nothing down for more than a few hours matters on its own because of dehydration, and it matters more after bowel surgery.
Say the word out loud when you ring. Wind, urine, stool, discharge, erection, incontinence — the person on the phone hears these all day and cannot help with a euphemism. A softened description is the commonest reason a serious symptom is filed as minor.
Blood is worth describing precisely, not minimising: how much, what colour, where from, how many times. “A bit of blood” covers everything from a spot to a litre.
What came home with you, and how each one fails
Know before you need to know
Who to ring out of hours, and the number written down, not in a leaflet
When the dressing comes off, and whether you may shower before then
When stitches or staples come out, and who does it
Which tablets are for how long, and which have stopped
When the review appointment is, and whether it exists yet
What was actually done — the words, so you can repeat them
The specific failures
A drain that stops draining, or suddenly fills, or falls out
A catheter that stops draining, leaks around itself, or hurts
A cast that becomes tight, or toes and fingers that go numb, pale or cold
A dressing soaked through rather than spotted
A stoma that stops working, or skin around it that breaks down
A wound left uncovered on the assumption that air is good for it
Write the out-of-hours number on the fridge before you need it. The surgical ward, the day-surgery unit or the number on the discharge letter — whichever it is, at three in the morning nobody can find a leaflet, and the default becomes waiting until Monday. Put it where the person looking after you can see it too.
Getting up, eating, driving, working
Get up and move every hour you are awake, and sit up to eat. Short and often beats one long walk. Lying flat all day is what causes most of what people fear.
Deep breaths and a cough, hourly, hurt and are the point. Hold a folded towel against an abdominal wound to make it bearable. This is what keeps the bases of the lungs open.
Eat protein and drink more than you feel like. Healing needs both, appetite comes back slowly, and dehydration makes the constipation and the dizziness worse.
Driving is not about the days, it is about whether you can do an emergency stop without hesitating, and about whether your insurer and the surgeon agree. Ask specifically rather than assuming a number, and try the movement stationary first.
Going back to work too early and too fully is the commonest cause of a long recovery, and a phased return is a normal request. Ask what the restriction actually is — lifting, driving, standing — because “take it easy” is not a plan.
If you live alone, arrange the first forty-eight hours before the operation, not after. Somebody to ring, somebody who can come, and food that needs nothing done to it. Ask for a district nurse or a hospital social worker if there is nobody.
Alcohol interacts with the painkillers, the wound and your judgement. Leave it until the strong painkillers have stopped.
What people believe, and what is so
Believed
Ringing about a wound is making a fuss
Some redness is normal, so redness is normal
Resting completely is the safest thing to do
They would have told me if it was serious
Air is good for a wound
If I can walk to the kitchen I can drive
The pain means the operation did not work
Actually
A wound check is a five-minute, entirely routine call
Spreading redness is the signal; the pen line settles it
Lying still is what causes clots and chest infections
Most complications appear after you get home
Most modern wounds do better covered as instructed
Driving is about the emergency stop and the insurer
Increasing pain is a signal; easing pain is the normal shape
The drill: 16 decisions
Sixteen ordinary evenings at home — the wound that looks redder, the calf that aches, the day-four fever, the painkiller that ran out on a Sunday. Most have an instinctive answer that feels considerate and costs you a week. Pick your move; every answer explains why.
