Skin lumps and bumps are common, and one of the frequent culprits is a sebaceous cyst or infected abscess. These growths often appear behind the ear, on the scalp, neck, or other oily areas of the body. While they might look alarming, especially when filled with pus or thick material, they are usually benign and treatable.
What Is a Sebaceous Cyst?
A sebaceous cyst is a noncancerous bump beneath the skin that develops when sebaceous glands (oil glands) or hair follicles become blocked. The cyst is usually filled with keratin, sebum, or pus-like material, giving it a whitish or yellow appearance.
Common features include:
-
A round, smooth lump under the skin.
-
Slow growth over time.
-
Yellowish or whitish discharge if squeezed.
-
Tenderness or redness if infected.
How Infections Occur
When bacteria enter a sebaceous cyst or clogged pore, it can turn into an infected abscess. The area becomes swollen, red, painful, and filled with pus. In severe cases, multiple pockets of pus may form, which can burst or require medical drainage.
Symptoms of Infected Cysts and Abscesses
-
Swelling and tenderness in the affected area.
-
Redness and warmth of the skin.
-
Thick, yellow or green pus discharge.
-
Foul smell in some cases.
-
Pain that worsens over time.
Treatment Options
-
Medical Drainage
-
A healthcare provider may perform a minor surgical procedure to drain the pus and relieve pressure.
-
-
Antibiotics
-
If the infection is severe, oral antibiotics may be prescribed to fight the bacteria.
-
-
Cyst Removal
-
To prevent recurrence, the entire cyst wall must be surgically removed.
-
-
Home Care
-
Warm compresses can help small cysts drain naturally.
-
Avoid squeezing or popping, as it may spread infection deeper.
-
When to See a Doctor
Seek medical attention if you notice:
-
Rapid swelling or spreading redness.
-
Fever or general illness.
-
Recurring cysts that keep coming back.
-
Large, painful lumps interfering with daily life.
Conclusion
Sebaceous cysts and infected abscesses are usually not life-threatening but can be very uncomfortable and unsightly. Early medical intervention helps prevent complications and ensures proper healing. If you or someone you know experiences similar symptoms, consult a healthcare professional for safe and effective treatment.
