Scars form as part of the natural healing process after an injury to the skin. Most scars remain stable over time, but sometimes they can change in shape, size, or texture. These changes may be harmless, but they can also signal an infection, allergic reaction, or other complications that need attention.

In this guide, you will learn:

• What changes in a scar are safe to monitor at home
• Which signs mean you should avoid self-treatment
• When to seek urgent care or call 911

Always remember, if you notice sudden, severe pain, spreading redness, swelling, pus, fever, or any rapidly worsening symptoms, call 911 or your local emergency services immediately. Prompt action can prevent serious complications.

Recognizing symptoms and danger signs when a scar changes shape or texture

When a scar changes shape or texture, it is important to observe the symptoms carefully. Scars can vary in appearance, but some changes may signal a need for medical attention. Understanding the difference between mild, moderate, and severe symptoms helps you decide what to do next.

Mild symptoms

• Scar feels slightly raised or itchy
• Minor redness or slight colour change around the scar
• Small areas of dryness or flaking skin

These mild symptoms can usually be managed safely at home. Keep the area clean and moisturized. Avoid scratching or picking at the scar to prevent irritation or infection.

Moderate symptoms

• Noticeable thickening or hardening of the scar
• Increased redness or swelling that does not improve within a few days
• Persistent pain or tenderness around the scar

If you experience moderate symptoms, monitor the scar closely. Avoid applying any creams or treatments not recommended by a healthcare provider. If symptoms worsen or do not improve within a week, seek advice from a healthcare professional or visit urgent care.

Severe symptoms and red flags

• Rapid changes in scar size, shape, or texture
• Open wounds, bleeding, or oozing pus from the scar
• Severe pain, spreading redness, or warmth around the scar
• Signs of infection such as fever, chills, or feeling unwell

These signs suggest an emergency situation. Call 911 or your local emergency services immediately if you notice any severe symptoms. Prompt medical care is essential to prevent complications.

Immediate first aid steps when a scar changes shape or texture

When a scar changes shape or texture, it is important to act carefully and promptly. These changes may signal an infection, allergic reaction, or other complications that need attention. Here are safe first aid steps you can take at home while waiting for professional help.

What you can do right away

• Keep the area clean by gently washing with mild soap and water. Avoid scrubbing the scar.
• Apply a cool, damp cloth to reduce any swelling or discomfort.
• Use a sterile, non-stick dressing if the scar is open or oozing to protect it from dirt and bacteria.
• Monitor the scar closely for any signs of worsening, such as increased redness, warmth, pain, or discharge.
• Take over-the-counter pain relievers like acetaminophen or ibuprofen if needed, following the label instructions.

What to avoid

• Do not apply creams, ointments, or home remedies without advice from a healthcare professional.
• Avoid scratching, picking, or rubbing the scar, as this can worsen irritation or cause infection.
• Do not cover the scar with tight or non-breathable materials that may trap moisture.

When to seek urgent care

Call 911 or go to the emergency department immediately if you notice:

• Rapidly spreading redness or swelling around the scar.
• Severe pain that does not improve with pain relief.
• Fever above 38°C (100.4°F) or chills.
• Any signs of pus or foul-smelling discharge.
• Difficulty moving the area near the scar or numbness.

For less urgent concerns, visit your family doctor or urgent care centre promptly. Early assessment helps prevent complications when a scar changes shape or texture.

What NOT to do when a scar changes shape or texture

When a scar changes shape or texture, certain actions can make the problem worse. Avoid these common mistakes to protect your health and prevent complications.

Do NOT pick or scratch the scar

Picking, scratching, or rubbing the scar can cause irritation, infection, or further damage. Keep the area clean and avoid touching it unnecessarily.

Do NOT apply unapproved creams or remedies

Do not use over-the-counter creams, oils, or home remedies that are not recommended by a healthcare professional. Some products can cause allergic reactions or worsen the scar’s condition.

Do NOT ignore signs of infection or rapid changes

If the scar becomes red, swollen, painful, or starts to ooze pus, do not delay seeking medical help. These signs may indicate an infection that requires prompt treatment.

Do NOT expose the scar to direct sunlight without protection

Sun exposure can darken or damage the scar tissue. Always cover the scar or use a broad-spectrum sunscreen if you must be outdoors.

When to call 911 or seek urgent care

• If the scar changes shape or texture rapidly and is accompanied by severe pain, spreading redness, fever, or difficulty moving the affected area, call 911 immediately.
• If you notice any sudden swelling, bleeding, or signs of a severe allergic reaction, seek emergency care without delay.

When to call 911 or seek urgent care for scar changes

Knowing when to call 911 or seek urgent care can protect your health and prevent complications. Call 911 immediately if you experience life-threatening symptoms such as severe bleeding that won’t stop, difficulty breathing, chest pain, sudden weakness, or loss of consciousness.

If your scar changes shape or texture, watch closely. This can sometimes signal infection or other issues. Seek urgent care or go to the emergency department if you notice:

• Rapid swelling, redness, or warmth around the scar
• Increasing pain or tenderness
• Discharge of pus or foul-smelling fluid
• Fever above 38°C (100.4°F)
• Scar opening or bleeding that won’t stop

For less urgent concerns, such as a scar that changes colour slowly or mild itching, a visit to your family doctor or a walk-in clinic is appropriate. They can assess the scar and recommend treatment or monitoring.

Avoid trying to cut, squeeze, or apply strong chemicals to the scar at home. These actions can worsen the problem or cause infection.

When in doubt, it is safer to seek professional advice promptly. Early care can prevent complications and support healing.

Ongoing care and follow-up when a scar changes shape or texture

After the initial injury or wound has been treated, ongoing care is important to ensure proper healing and to prevent complications.

• Gently clean the area with mild soap and water as needed.
• Apply a clean, dry dressing if recommended to protect the wound.
• Use over-the-counter pain relief, such as acetaminophen or ibuprofen, following the package directions.

What to avoid

• Do not apply creams, ointments, or home remedies unless advised by a healthcare professional.
• Avoid strenuous activity that may reopen or stress the wound.

When to seek medical advice

• Signs of infection that do not improve or worsen after 24-48 hours.
