Safely Managing an Infected Epidermal Cyst: Drainage and Aftercare

An epidermal cyst is a small, benign bump under the skin, often filled with keratin. While usually painless and harmless, these cysts can become infected, leading to swelling, redness, tenderness, and pus formation. When this happens, drainage may be necessary to relieve discomfort and prevent further complications.

When Is Drainage Required?

If a cyst becomes painful, red, or starts oozing pus, it may be infected. In such cases, medical drainage is often needed. Attempting to pop or squeeze the cyst at home is strongly discouraged, as it can worsen the infection or cause scarring.

The Drainage Procedure

A healthcare professional will typically perform the drainage under sterile conditions. After cleaning the area, a small incision is made to allow the infected contents to drain. Sometimes, the cavity may be irrigated with saline to flush out any remaining debris or pus. In certain cases, a small gauze wick or drain may be placed to keep the site open for continued drainage.

Aftercare and Healing

Post-procedure care is essential to promote healing and prevent recurrence. This includes:

• Keeping the area clean and dry

• Applying any prescribed antibiotic ointments

• Taking oral antibiotics if prescribed

• Attending follow-up appointments if needed

Avoid picking at or pressing on the area as it heals. The cyst sac might not be removed during drainage, so recurrence is possible. For permanent resolution, a minor surgical excision might be recommended after the infection has cleared.
