Signs of infection after scar revision can include redness that spreads beyond the incision, increasing warmth or swelling, worsening pain, thick yellow or green drainage, a bad smell, fever, chills, or wound edges pulling apart. Some redness and tenderness can occur during normal healing, but symptoms that worsen, new drainage, or fever need prompt medical advice. Contact your surgeon rather than waiting for your next routine visit.
What are the signs of infection after scar revision?
After scar revision surgery, an infection may affect the skin around the incision or the tissue underneath it. Changes in the wound's appearance, how it feels, and your general well-being can provide important clues. Signs to watch for include the following:
- Increasing redness or skin discoloration: The area around the incision may become progressively redder or develop a change in color that spreads beyond the original wound edges.
- Warmth and swelling: The skin around the scar may feel noticeably hotter than nearby skin or become increasingly swollen.
- Worsening pain or tenderness: Pain may increase rather than gradually improve, or the incision may become more painful when touched gently.
- Pus or unusual drainage: Thick, cloudy, yellow, green, white, or cream-colored fluid may appear at the incision. An unpleasant smell can accompany the drainage.
- An opening in the incision: The wound edges may separate, or the incision may appear wider or deeper instead of remaining closed.
- Fever, chills, or feeling unwell: You may develop a raised temperature, shivering, sweating, or a general feeling of illness alongside changes at the surgical site.
The Cleveland Clinic identifies spreading redness, warmth, tenderness, pus, an unpleasant odor, wound opening, fever, and chills as possible signs of a surgical wound infection. These symptoms may occur individually or together, and their significance depends on the overall clinical picture.
How can you tell infection signs from normal healing?
Some redness, swelling, bruising, and tenderness can occur during the early stages of recovery after surgery. Their presence alone does not necessarily mean that an infection has developed. What matters is how the wound changes over time. Symptoms that steadily worsen, redness that spreads, increasing heat or pain, or new pus-like drainage deserve medical attention.
The Royal Orthopaedic Hospital notes that some redness and swelling are expected after surgery but advises watching for increasing soreness, heat, colored discharge, fever, or feeling generally unwell. When checking your scar, consider changes in its appearance alongside pain, swelling, drainage, and how you feel overall.
How soon after scar revision can an infection develop?
An infection can develop within the first few days after surgery, but it is not limited to that early period. The incision remains vulnerable while it heals, so new or worsening symptoms should be taken seriously even if the first part of recovery seemed uneventful.
University College London Hospitals (UCLH) explains that surgical wound infections may develop from about two to three days after an operation until the wound has fully healed, which commonly takes around two to three weeks. Healing time varies with the procedure and individual circumstances, so these time frames should not be used to rule out an infection.
When should you contact your surgeon?
Contact your surgeon or the clinic that performed your scar revision promptly if you notice pus, a bad smell, spreading redness, increasing warmth or swelling, worsening pain, a wound that is opening, fever, or chills. Do not wait for your next scheduled appointment if these changes develop. Follow any specific instructions you received about whom to contact during recovery.
MedlinePlus advises contacting a surgeon when a surgical wound develops signs such as redness, tenderness, heat, pus or other drainage, a bad smell, fever, or chills. During an assessment, a healthcare professional may examine the incision, ask when symptoms began and whether they are worsening, and take a sample of wound drainage when appropriate.
When is emergency medical care necessary?
Seek emergency medical care if you have possible wound infection symptoms accompanied by confusion, shortness of breath, clammy or sweaty skin, extreme pain or discomfort, or severe shaking chills or a feeling of being very cold. These may be warning signs of sepsis, a life-threatening response to infection that requires immediate evaluation.
The U.S. Centers for Disease Control and Prevention (CDC) advises that people with possible sepsis symptoms need immediate medical assessment. Do not delay emergency care while waiting to speak with your surgeon if these warning signs occur.
What should you do while waiting for medical advice?
Keep the incision protected according to your surgeon's wound-care instructions. Wash your hands before handling any dressing, and avoid squeezing the wound, pulling at stitches, or trying to drain fluid yourself. Do not apply antibiotic creams, antiseptics, cosmetics, or other products to the incision unless your surgical team has instructed you to do so. These steps help avoid unnecessary irritation or disruption while you arrange an assessment.
Do not start leftover antibiotics or use someone else's medication. The appropriate next steps depend on the wound's appearance, your symptoms, your medical history, and the examination findings. Early assessment can help the healthcare team determine whether infection is present and whether treatment is needed.
