What Is a Carbuncle?
A carbuncle is a skin growth that becomes red, swollen, painful, and itchy. It is a type of progressive bacterial infection characterized by a firm lump with multiple pus-filled cores.
A carbuncle develops as a progression of folliculitis, advancing in the following stages. Furuncles and carbuncles may also be accompanied by fever and fatigue.
- Folliculitis
- Furuncle
- Furunculosis
- Carbuncle
Because topical treatments alone are often insufficient, please seek medical attention as soon as you notice symptoms.
What Causes a Carbuncle?
Carbuncles are caused by infection of small wounds or hair follicles with Staphylococcus aureus.
Staphylococcus aureus is a bacterium that normally lives on the surface of the skin as part of the natural flora.
However, changes in living environment and other factors can disrupt the balance of resident bacteria or weaken the immune system, making infections more likely to occur.
Because carbuncles can recur repeatedly unless the underlying cause is addressed, chronic cases require not only treatment but also a review of lifestyle habits and living conditions.
What Happens When You Develop a Carbuncle? Symptoms Explained
When a carbuncle develops, the following symptoms may appear.
- Pain
- Redness
- Swelling
- Multiple pustules
- Fever
- Fatigue
A carbuncle is characterized by a lump that can grow from the size of a hen’s egg to the size of a palm, with spreading redness and pain. Multiple white pustules also form at the center of the affected area.
As the condition progresses, the skin surface may become necrotic or discharge pus, so prompt attention is important.
Carbuncles develop as a progression of folliculitis and furuncles.
The symptoms of folliculitis, furuncles, and carbuncles are as follows.
| Type of Skin Condition | Description |
|---|---|
| Folliculitis | ・Mild pain ・Redness ・Small amount of pus |
| Furuncle | ・Severe pain ・Redness ・Swelling ・Firm pus plug ・Fever ・Fatigue |
| Carbuncle | ・Involves multiple hair follicles ・Severe pain ・Redness ・Swelling ・Multiple pustules |
A carbuncle is a skin infection. Self-treatment with topical medications is often insufficient, so please seek medical attention as early as possible.

How Are Carbuncles Examined and Diagnosed?
There are two main methods used to examine carbuncles.
- Bacterial culture test
- Blood test
If a carbuncle is suspected, the pus is cultured to identify the causative bacteria. When a carbuncle is present, bacteria such as Staphylococcus aureus and Staphylococcus epidermidis are typically detected.
In addition, a blood test may show an elevated white blood cell count and elevated CRP levels. CRP (C-reactive protein) is a protein that increases in the blood when inflammation or tissue damage occurs.
Can Carbuncles Heal on Their Own? Treatment for Carbuncles and Furuncles
Carbuncles and furuncles do not resolve on their own, except in very mild cases.
Treatment approaches for carbuncles and furuncles are as follows.
| Symptoms | Treatment | |
|---|---|---|
| Mild | ・No pus drainage or pustules | ・Antibiotics |
| Moderate | ・With pus drainage | ・Antibiotics ・Incision and drainage |
| Severe | ・Spreading inflammation ・With pus drainage ・Foul odor |
・Antibiotics ・Incision and drainage ・Wound irrigation |
Carbuncles and furuncles are treated with antibiotics selected based on the causative bacteria.
However, since identifying the specific bacteria takes several days, treatment is typically started with antibiotics considered likely to be effective against staphylococci, which are the most common causative organisms.

How to Prevent Carbuncles
To prevent carbuncles, it is important to maintain the skin’s barrier function and immune defenses to reduce the risk of infection by resident bacteria.
Specific measures to support immune health include the following.
- Maintain a regular daily routine
- Get sufficient sleep
- Take regular breaks to manage stress
- Treat any existing skin inflammation promptly
When the skin’s barrier function and immune system are in good condition, the likelihood of infection is reduced even if bacteria are present on the skin. Practice daily skincare and be mindful of your living environment to help maintain healthy skin.
Frequently Asked Questions About Carbuncles
Below are answers to frequently asked questions about carbuncles.
Is It Okay to Drain the Pus from a Carbuncle or Furuncle?
Draining the pus from a carbuncle or furuncle may help speed up recovery. In a medical setting, when pus has accumulated, the area may be incised and irrigated as part of treatment.
However, attempting to drain pus on your own can further damage the skin and may worsen the infection or slow healing. If pus has accumulated, please consult a physician.
What Is the Relationship Between Carbuncles/Furuncles and Diabetes?
When conditions such as diabetes or malignant tumors are present as comorbidities, carbuncles and furuncles may progress rapidly.
Older adults in particular are at higher risk of immune compromise due to underlying conditions, so the presence of comorbidities will be assessed during the consultation.
