What should you know about a cyst inside the skin?

Short answer
A cyst inside the skin is usually a contained lump beneath the surface, but pain, redness, drainage, or growth calls for medical assessment.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

What is beneath the surface
An epidermoid cyst is a sac under the skin that can collect keratin. It may feel smooth, round, and firm, and it can move slightly under gentle pressure. Some cysts have a small opening, while others do not. They may stay the same for a long time, then swell after rubbing or inflammation. A red, painful lump can also be an abscess or another skin condition, so a label based only on a photograph or feel can be misleading. The exact depth, skin changes, and symptoms guide assessment.
What you can do
Leave the surface intact and avoid needles, squeezing, or forceful massage. Keep it clean, protect it from friction, and note whether its size, colour, tenderness, or drainage changes. A clinician may monitor a quiet cyst, treat inflammation with an injection, drain an abscess, or discuss removal when the cyst repeatedly troubles you. Read more about [Skin Lumps](/symptoms/skin-lumps/) and possible [Cyst Removal](/treatments/surgical-dermatology/cyst-removal/).
When to seek care
Get prompt medical advice for increasing pain, warmth, redness, pus, fever, or swelling that develops quickly. Arrange an examination for a lump that is hard, fixed, rapidly changing, repeatedly returning, or associated with an open area of skin. Severe pain with feeling unwell needs urgent care. Do not assume every deep lump is a cyst, particularly when its borders or location are unclear.
Questions to bring
Does this feel like an epidermoid cyst or an abscess? Is it superficial or deeper? Would watching it be reasonable? If treatment is needed, what are the options and what warning signs should I monitor?

Questions people ask
Can a cyst under the skin disappear?
Some remain quiet or become less noticeable, but a persistent or recurrent lump should still be assessed rather than repeatedly squeezed.
What is the difference between a cyst and an abscess?
A cyst is a contained sac, while an abscess is a collection of pus linked with infection; redness, heat, pain, and fever favour prompt assessment.
