The short explanation
Redness, warmth and cloudy fluid from a caesarean scar can be signs of a wound infection, and it should be checked the same day. Wound infections after caesarean are not unusual, and early treatment usually works well. A small amount of clear fluid can sometimes come from a healing wound, but cloudy or smelly fluid, spreading redness, increasing pain or fever point towards infection.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Diabetes, a higher body weight, anaemia, a long labour before surgery or an emergency operation can make infection more likely.
- Until you are seen, keep the wound clean and dry, wear loose cotton clothing, and avoid applying creams, powders or home remedies unless a clinician has advised them.
- Your surgeon or the hospital where you delivered is often the best place to go, as they know the operation.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether the wound is infected or whether fluid has collected under the skin. A clinician needs to examine it and may take a swab or do a scan.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is the wound infected, and how deep is it?
- Does any fluid need to be drained?
- Is the treatment safe while breastfeeding?
- How should I dress and clean the wound?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you have a high fever with shivering, feel confused, very drowsy or breathless, or feel extremely unwell.
- Call 112 also if the wound opens widely or you have severe belly pain.
Get help the same day
- Get the wound examined today if there is cloudy fluid, spreading redness, increasing pain or fever.
Book an appointment soon
- Go back within a few days if it has not improved after treatment starts.
Raise it at a routine appointment
- Check scar healing at your routine postnatal visit.
