In short. The first 48 hours at home after surgery follow a predictable pattern: swelling begins within hours and peaks around the second or third day, bruising may spread downwards, and drowsiness and a low temperature are common. Discomfort should be controlled and easing, not severe or worsening, and findings that are not normal need same-day contact.
Key points
- Swelling begins within hours and peaks around the second or third day.
- A low temperature can follow surgery without meaning infection.
- Take pain relief on the prescribed schedule, even while numbness remains.
- Severe or worsening pain, a soaked dressing or chest pain needs immediate contact.
- Do not drive, make decisions or sign anything while taking strong pain relief.
What the first two days at home are for
The first two days at home decide how smoothly the rest of your recovery goes. Most of what happens in that window is predictable, and knowing which sensations are expected makes it far easier to notice the ones that are not.
You will be discharged only when your breathing, circulation and pain are stable, and you will leave with written instructions from the team that treated you. Those instructions are specific to your operation. Where anything on this website differs from what your own discharging team wrote down, theirs is the version to follow.
Arrange for someone to stay with you for the first night. Anaesthesia and pain relief both make people drowsy, and a second pair of eyes watching for changes is the single most useful thing you can organise in advance.
What is normal in the first 48 hours
Swelling begins within hours and peaks around the second or third day. Bruising appears and may spread downwards with gravity. The wound feels tight, the area feels numb or oddly sensitive, and a low temperature can follow surgery without meaning infection. Drowsiness, a sore throat from the breathing tube, a dry mouth, and light-headedness when standing up quickly are all common. Discomfort should be present but controlled, and it should be easing rather than building.
How should pain relief be taken?
Take your pain relief on the schedule your discharging team set out, even on the first day when the numbness has not yet worn off. Staying ahead of pain is easier than catching up with it, and it lets you move, breathe deeply and sleep, all of which help healing.
Which findings need same-day attention?
Some findings need attention the same day: pain that is severe, or that is getting worse rather than better; bleeding that soaks through a dressing, or a dressing that keeps seeping; a wound that opens; redness or warmth spreading beyond its edges; a high temperature; swelling that becomes sudden, hard and one-sided; a calf that is swollen, tender and warm; chest pain or breathlessness; a skin flap or graft that turns dark, grey or cold. Any of these is a reason to contact the hospital immediately, not at your next appointment.
| Finding | Expected in the first 48 hours | Not normal | What to do |
|---|---|---|---|
| Pain | Present but controlled, easing rather than building | Severe, or getting worse rather than better | Contact the hospital immediately |
| Swelling | Begins within hours, peaks around the second or third day | Sudden, hard and one-sided | Contact the hospital immediately |
| Temperature | A low temperature can follow surgery without meaning infection | A high temperature | Contact the hospital immediately |
| The wound | Feels tight, numb or oddly sensitive | The wound opens | Contact the hospital immediately |
| Bleeding | A dressing is in place over the wound | Bleeding soaks through it, or it keeps seeping | Contact the hospital immediately |
| Redness or warmth | Not described as expected | Spreading beyond its edges | Contact the hospital immediately |
| Leg or chest symptoms | Not described as expected | A swollen tender warm calf, chest pain or breathlessness | Contact the hospital immediately |
Resting well in the first two days
Sleep when you are tired, keep the area elevated if your operation allows it, and drink fluids regularly. Eat something light if you feel able. Do not drive, do not make important decisions, and do not sign anything while you are still taking strong pain relief.
What does it mean if the second day brings no improvement?
By the end of the second day most people notice that the worst has passed. If it has not, that is itself information worth passing on to your team.

Frequently asked questions
What is normal swelling in the first two days?
Swelling begins within hours and peaks around the second or third day. Bruising appears and may spread downwards with gravity. Discomfort should be present but controlled, and should be easing rather than building.
Should I take pain relief before the numbness wears off?
Yes. Take it on the schedule your discharging team set out, even on the first day. Staying ahead of pain is easier than catching up with it, and it lets you move, breathe deeply and sleep, all of which help healing.
Which findings in the first 48 hours need same-day attention?
Pain that is severe or worsening, bleeding that soaks a dressing, a wound that opens, spreading redness or warmth, a high temperature, sudden hard one-sided swelling, a tender swollen calf, chest pain or breathlessness.
Risks & Limitations
- Recovery takes longer than most patients expect, and the final result of most operations is judged at six to twelve months, once swelling has settled and scars have matured.
- Some swelling, bruising, numbness and discomfort are a normal part of healing rather than a sign that something has gone wrong.
- Scars are permanent, though they mature and usually become softer and less noticeable over twelve to eighteen months.
- Rushing back to activity commonly causes setbacks and costs more time than it saves.
- The written instructions from your own discharging team override any general guidance here, including on dressings, medication, activity and follow-up.
When to Seek Care
- Severe or worsening pain, or a wound that opens or discharges.
- Spreading redness or warmth around the wound, or a fever.
- A swollen, painful calf; chest pain; or breathlessness — seek emergency care immediately.
- Heavy bleeding, or a dressing that is soaked through.
- A flap or graft that turns dark or cold.
- Do not wait for your next appointment for any of these. Contact your own clinical team, and if the problem is severe and you cannot reach them, go to an emergency department.
