Lump Under the Skin in the Genital Area: What to Know

Friction, shaving, waxing, sweat, and an ingrown hair can inflame a follicle and create a sore bump. A blocked gland may produce a deeper, smooth cyst. A boil is usually tender, warm, swollen, and sometimes drains; learn more about [Boils](/conditions/boils/). A lump can also arise from tissue beside the genital skin, so its exact position matters. [Skin Lumps](/symptoms/skin-lumps/) covers the wider symptom. Appearance alone cannot distinguish irritation from every other cause, and a genital lump is not automatically a sexually transmitted infection or cancer.

Do not squeeze, pierce, shave over, or apply fragranced products to the lump. Gently wash, pat dry, choose loose breathable clothing, and reduce friction until the skin settles. Avoid sexual contact if movement causes pain, the skin is open, or there is unexplained discharge; a clinician can advise about testing when relevant. Record the site, onset, tenderness, drainage, and whether it is changing. A dermatology or sexual-health clinician can examine you privately. [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/) may be discussed for selected inflamed lesions, not as a general treatment for every lump.

Seek urgent help for severe pain, rapidly spreading redness, fever, rapidly increasing swelling, difficulty passing urine, or feeling very unwell. Arrange a prompt examination if the lump persists, enlarges, becomes hard or fixed, bleeds, ulcerates, repeatedly returns, or is associated with a new sore or ongoing discharge. These features are reasons to examine the area, not proof of a serious diagnosis. A persistent changing skin lesion may require assessment for conditions such as [Basal Cell Carcinoma](/conditions/basal-cell-carcinoma/).

Ask whether the lump is a follicle, cyst, boil, lymph node, or another structure. Ask whether infection or sexual-health testing should be considered, which products and activities to avoid, whether treatment is needed, and how soon a change should be reviewed.
