When you get a cut, your body naturally begins the healing process—but sometimes, things don’t go as planned. What starts as a minor scrape can quickly become a serious problem if an infection sets in. Knowing how to tell if a cut is infected or healing is key to protecting your health and avoiding complications. This guide will help you recognize early signs, understand what’s normal, and take action fast.
Top Key Takeaways
A healing cut gradually improves in appearance—less redness, less pain, and no spreading swelling.
Infected cuts often get worse over time, showing signs like increased redness, pus, warmth, or red streaks.
Prompt care and cleanliness are essential to avoiding infections.
Never ignore a worsening wound, especially if you develop a fever or chills.
Seek professional medical care if your symptoms escalate or don’t improve in 5–7 days.
Signs Your Cut Is Healing Normally
Healing is a natural process that happens in stages. Here’s what a healing cut typically looks like:
Scabbing or clotting at the wound site
Decreasing redness over time
Mild itchiness or tightness as new skin forms
No pus, spreading, or unusual odor
Gradual reduction in pain and tenderness
These are all signs your immune system is doing its job.
Signs Your Cut May Be Infected
In contrast, an infected cut may show symptoms that get worse rather than better. Watch for:
Redness that expands outward
Warmth or swelling around the area
Yellow or green pus or cloudy drainage
Bad odor from the wound
Increased pain or throbbing
Fever, chills, or fatigue
Red streaks extending from the wound toward the heart
Any of these could indicate a spreading infection and require immediate attention.
Expert Says
“Early infection signs like warmth, pus, and expanding redness should never be ignored,” says Dr. Melissa Tran, a board-certified dermatologist.
“The sooner you act, the more likely you’ll avoid serious complications like cellulitis or sepsis.”
When to Act Fast
Get medical help right away if:
Red streaks form near the cut
You experience a fever or feel ill
The wound looks worse after several days instead of better
There’s a foul odor or increasing discharge
Pain becomes severe or unmanageable
Delaying care may lead to deeper infection or longer healing time.
What’s Next: Safe Wound Care Tips
Clean the cut gently with mild soap and water
Apply an antibiotic ointment and cover with a sterile bandage
Change the dressing daily or if it becomes dirty or wet
Avoid scratching or picking at the scab
Monitor daily for signs of infection
Call a doctor if things don’t improve within a few days
Proper wound care can prevent most infections from developing.
Final Thoughts: Don’t Wait to Intervene
Understanding how to tell if a cut is infected or healing can be the difference between a quick recovery and a major medical issue. When in doubt, it’s always safer to get a second opinion. By keeping your cut clean, watching for warning signs, and acting quickly, you give your body the best chance to heal safely and completely.

You can usually shower, but avoid soaking the wound. Pat it dry and apply a clean dressing afterward.

Clear or slightly yellow fluid can be normal. Green, thick, or foul-smelling pus is a sign of infection.
