Skin cysts are common, usually harmless lumps that develop beneath the skin. However, when a cyst becomes infected, it can turn painful, swollen, and dangerous if not treated properly. Infected skin cysts often appear red, inflamed, and may discharge pus, causing discomfort and concern.
This article explains what infected skin cysts are, why they occur, how to recognize them, and the safest treatment options.
🎺What Is an Infected Skin Cyst?
A skin cyst is a closed sac under the skin filled with fluid, keratin, or other material. When bacteria enter the cyst—often through a small break in the skin—it can become infected. This infection triggers inflammation, pus formation, and tissue damage around the cyst.
Common types of cysts that may become infected include:
-
Epidermoid cysts
-
Sebaceous cysts
-
Pilar (hair follicle) cysts
👉Common Causes of Infection
Several factors can lead to cyst infection:
-
Blocked hair follicles
-
Excess oil production
-
Poor hygiene
-
Shaving or skin irritation
-
Skin trauma or scratching
-
Attempting to squeeze or pop a cyst
-
Weakened immune system
Once bacteria enter the cyst, the body responds with inflammation, leading to swelling and pain.
🔥Signs and Symptoms of an Infected Cyst
An infected cyst often shows clear warning signs, including:
-
Redness and warmth around the area
-
Swelling that increases over time
-
Pain or tenderness when touched
-
Thick yellow or white pus drainage
-
Foul odor from the discharge
-
Fever or general discomfort (in severe cases)
-
Skin discoloration or darkened center
If left untreated, the infection can spread to surrounding tissue.
🌞Why You Should Not Pop an Infected Cyst
Many people attempt to squeeze cysts at home, which can make the condition worse. Popping an infected cyst can:
-
Push bacteria deeper into the skin
-
Increase inflammation and pain
-
Cause scarring
-
Spread infection to nearby areas
-
Lead to abscess formation
Medical treatment is always safer than home manipulation.
⚡Medical Treatment Options
Treatment depends on the severity of the infection:
1. Antibiotics
Doctors may prescribe oral or topical antibiotics to control bacterial growth.
2. Incision and Drainage
For large or painful cysts, a healthcare professional may drain the cyst using sterile tools.
3. Surgical Removal
If cysts keep returning, complete surgical removal of the cyst wall may be recommended to prevent recurrence.
4. Pain and Inflammation Management
Anti-inflammatory medications can help reduce swelling and discomfort.
🔑Home Care (Only for Mild Cases)
If advised by a doctor, mild cysts may benefit from:
-
Warm compresses to promote drainage
-
Keeping the area clean and dry
-
Avoiding tight clothing that causes friction
Never attempt home remedies for severe or worsening infections.
🔆When to See a Doctor Immediately
Seek medical attention if:
-
Pain increases rapidly
-
Fever develops
-
The cyst grows larger or turns dark
-
Red streaks appear around the area
-
Pus continues draining for several days
These signs may indicate a spreading infection.
🎊Possible Complications if Untreated
Ignoring an infected cyst can lead to serious issues such as:
-
Abscess formation
-
Skin necrosis
-
Scarring
-
Bloodstream infection (rare but dangerous)
Early treatment prevents long-term damage.
🔔Prevention Tips
To reduce the risk of infected cysts:
-
Maintain good skin hygiene
-
Avoid squeezing skin lesions
-
Use clean shaving tools
-
Treat acne and skin irritation early
-
Consult a doctor for recurring cysts
🔊Final Thoughts
Infected skin cysts are common but should never be ignored. While many cysts are harmless, infection can cause pain, scarring, and complications if left untreated. Proper medical care, early diagnosis, and avoiding home manipulation are key to safe recovery.
If you notice unusual swelling, pain, or discharge, consult a healthcare professional promptly.
