Skin cysts are common growths that develop beneath the skin. In many cases, they are harmless and painless. However, when a cyst becomes infected, it can quickly turn into a painful, swollen, and sometimes alarming skin condition. The images above show various stages of infected skin cysts, including redness, swelling, pus formation, and active drainage.
Understanding how infected cysts develop and how they should be treated is essential to prevent complications.
šWhat Is a Skin Cyst?
A skin cyst is a closed sac under the skin that contains fluid, keratin, oil, or other material. Common types include:
-
Epidermoid cysts
-
Sebaceous cysts
-
Pilar cysts
These cysts usually grow slowly and may remain unnoticed for years. Problems begin when the cyst becomes blocked, irritated, or infected.
šHow Does a Cyst Become Infected?
Infection occurs when bacteria enter the cyst through a tiny opening or break in the skin. Common causes include:
-
Blocked hair follicles
-
Excess oil production
-
Skin trauma or friction
-
Poor hygiene
-
Sweating and moisture
-
Attempting to squeeze or pop the cyst
-
Weakened immune system
Once bacteria enter, the body responds with inflammation, leading to pus accumulation and swelling.
šSigns and Symptoms of an Infected Skin Cyst
An infected cyst often shows clear warning signs, such as:
-
Redness and swelling around the cyst
-
Pain or tenderness
-
Warmth in the affected area
-
Pus-filled center (white, yellow, or green discharge)
-
Shiny, stretched skin
-
Crusting or scabbing
-
Unpleasant odor from drainage
-
Fever in severe cases
The images demonstrate active infection, where pus and inflammation are clearly visible.
šWhy Infected Cysts Should Not Be Ignored
Ignoring an infected cyst can lead to serious complications, including:
-
Abscess formation
-
Spread of infection to surrounding skin (cellulitis)
-
Permanent scarring
-
Recurrent infections
-
Tissue damage
-
Rarely, systemic infection if bacteria enter the bloodstream
Early medical care greatly reduces these risks.
šProper Treatment Options
Treatment depends on the severity of the infection and should always involve a healthcare professional.
1. Medical Drainage
A doctor may safely open and drain the cyst using sterile instruments to remove pus and reduce pressure.
2. Antibiotic Therapy
Topical or oral antibiotics may be prescribed to control bacterial infection.
3. Surgical Removal
If cysts recur or do not heal properly, complete removal of the cyst wall may be necessary to prevent future infections.
4. Supportive Care (Mild Cases Only)
-
Warm compresses (10ā15 minutes, several times daily)
-
Keeping the area clean and dry
-
Avoiding friction or pressure
ā ļø Never attempt to pop or drain a cyst at home, as this can worsen infection and increase scarring.
šWhen to Seek Medical Attention
You should consult a healthcare professional if:
-
The cyst becomes very painful
-
Redness spreads rapidly
-
Pus continues to drain
-
Fever develops
-
The cyst grows quickly
-
The infection keeps returning
Prompt treatment leads to faster healing and fewer complications.
šPrevention Tips
To reduce the risk of infected cysts:
-
Maintain good skin hygiene
-
Avoid squeezing or picking skin bumps
-
Wear breathable clothing
-
Treat acne and skin conditions early
-
Keep wounds clean and covered
-
Follow medical advice for recurring cysts
šFinal Thoughts
Infected skin cysts can appear severe and uncomfortable, but with proper medical care, most heal well without long-term problems. Recognizing the signs of infection and avoiding self-treatment are key steps in protecting skin health.
If you notice swelling, redness, pain, or pus, seek professional care rather than attempting to treat it yourself.
