Cyst on Hip Skin

A skin cyst is a sac under the surface, often containing keratin. On the hip, repeated pressure from sitting, tight clothing, belts, or exercise can make an otherwise quiet lump sore. It may feel firm or rubbery and may have a small central opening. A hip lump can have other causes, so a health professional should examine a new, persistent, or changing swelling. General information about [Skin Lumps](/symptoms/skin-lumps/) can help you describe what you notice.

Avoid squeezing or puncturing the area, since this can spread inflammation and introduce bacteria. Wear clothing that reduces rubbing, cleanse gently, and keep notes about tenderness, drainage, and growth. If the lump is repeatedly irritated, a clinician may discuss observation, [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/), or [Cyst Removal](/treatments/surgical-dermatology/cyst-removal/). The right option depends on whether the lump is inflamed and whether its sac needs to be removed.

Seek prompt care if the hip becomes hot, increasingly painful, red, swollen, or begins draining pus. Fever or redness that spreads beyond the lump can signal infection. A collection of pus may need [Abscess Drainage](/treatments/minor-procedures/abscess-drainage/) rather than home treatment. Get urgent advice if you feel markedly unwell or the swelling worsens quickly.

Could pressure or friction be aggravating this lump? Does it appear infected or inflamed? Would monitoring, an injection, drainage, or removal address the problem? How can I protect the area during sitting, exercise, or sleep?
