In short. Swelling and bruising after surgery follow a predictable curve: they begin within hours, peak around the second or third day, then settle over weeks to months. Normal swelling is gradual and improving; sudden hard one-sided swelling, rapidly expanding bruising, fever or breathlessness is not that curve and needs assessment. Results are judged at six to twelve months.
Key points
- Swelling begins within hours, peaks around day two or three, then falls steadily.
- Bruising moves through red, purple, green-yellow and brown, usually resolving in two to three weeks.
- Gravity pulls swelling and bruising downwards, which is why elevation helps.
- Swelling others notice usually goes by four to six weeks; deeper tissue refines until three to six months.
- Sudden hard one-sided swelling, spreading redness or breathlessness needs assessment, not waiting.
Why does swelling follow a predictable curve?
Recovery from surgery takes longer than almost everyone expects. A wound may close within a fortnight, but the tissue underneath keeps changing for a year, and knowing the sequence makes it easier to be patient with it. Swelling is fluid and inflammation collecting in the operated tissue, and it follows a predictable curve. It begins within hours, builds to a peak around the second or third day, and then falls steadily. Gravity moves it downwards, which is why bruising often appears below the operation site and why keeping the area elevated helps. Swelling is not uniform: some regions fill quickly and empty slowly, and the last part of it is always the slowest to go.
What colour changes does bruising go through?
Bruising changes colour in a sequence: red, then purple, then green-yellow, then fading brown. It can spread widely and look alarming without meaning anything is wrong. It usually resolves within two to three weeks, though a faint discolouration can persist longer in thin or sun-damaged skin. Bruising that appears suddenly, expands rapidly, or comes with a hard, tense and painful swelling is different, and should be reported.
The recovery timeline, week by week
| Stage | Swelling | Bruising | What else changes |
|---|---|---|---|
| First week | Begins within hours; peaks around day two or three, then falls | Appears, peaks and begins to fall; may spread downwards with gravity | Wound sealed and uncomfortable; tiredness |
| Second and third weeks | The worst of it goes | Most visible bruising fades; usually resolves within two to three weeks | You feel more like yourself but tire quickly |
| Four to six weeks | Gone to other people; still visible in the mirror and fluctuates through the day | A faint discolouration can persist in thin or sun-damaged skin | — |
| Three to six months | Deeper tissue softens | — | Contours refine |
| Six to twelve months | Change continues slowly beyond six months | — | The result is judged in this window |
| Scars, over twelve to eighteen months | — | — | Red and raised early, then flatten and fade |
Keeping a photographic record
Take a photograph in the same light and at the same angle every week, starting from before your operation. Swelling changes so gradually that memory adjusts to it, and patients who keep a record are usually far calmer at three months than those who rely on recollection.
What else is normal while swelling settles?
Numbness is expected and often outlasts the swelling. Sensation usually returns gradually over months, and a small patch may never feel exactly as it did. Firmness, lumpiness and a slightly irregular contour in the first months are part of healing, not a failure. Some asymmetry is normal, because faces and bodies are asymmetric before any operation. Scars are red and raised early, then flatten and fade, maturing over twelve to eighteen months.
When should you report rather than wait?
Report rather than wait if:
- Swelling becomes sudden, hard and one-sided, or increases again after it had been settling.
- Bruising expands rapidly, or the area becomes tense, shiny and severely painful.
- You develop fever, spreading redness, wound discharge, chest pain or breathlessness.
Why recovery is not a straight line
Recovery is not a straight line. Good weeks and disappointing weeks alternate, and a single swollen morning does not mean a setback. Judge your progress over months, and take your questions to your review appointments rather than to the internet.

Frequently asked questions
When does swelling reach its peak after surgery?
It begins within hours, builds to a peak around the second or third day, and then falls steadily. Gravity moves it downwards, which is why bruising often appears below the operation site and why elevation helps.
How long does bruising last?
Bruising changes colour in sequence and can spread widely without meaning anything is wrong. It usually resolves within two to three weeks, though a faint discolouration can persist longer in thin or sun-damaged skin.
When should the result of surgery be judged?
At six to twelve months. Deeper tissue softens and contours refine between three and six months, and change continues slowly beyond that. Judging earlier is unreliable in both directions, so a single swollen morning means little.
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.
