Hard Lump Under Skin on Cheek: What to Know

A tender, warm lump that develops quickly can fit an inflamed follicle or boil. A smoother, slower-growing bump may be a blocked skin structure or cyst. A firm area that follows an injury can reflect healing tissue. A cheek lump that persists, bleeds, crusts, forms an open sore, or changes in appearance needs an in-person assessment; a skin lump alone does not identify its cause.

Basal cell carcinoma is one condition a clinician may consider when a persistent facial growth has concerning surface changes. You can read about [Basal Cell Carcinoma](/conditions/basal-cell-carcinoma/) and general [Skin Lumps](/symptoms/skin-lumps/).

Do not squeeze, pierce, massage, or repeatedly press the area, because this can worsen inflammation and obscure its appearance. Wash gently, avoid irritating products over the bump, and take a dated photograph so you can compare changes. Record when it began, whether it moves under the skin, and whether pain, redness, drainage, or crusting occurs. Arrange a dermatology review if it remains or grows. Treatment depends on the examination; some inflammatory nodules may be considered for a Steroid Injection Into The Skin, but only after a clinician confirms it is suitable.

Seek prompt medical care if cheek swelling spreads, pain becomes severe, the skin is hot and markedly red, pus appears, or you develop fever. Arrange a timely appointment for a lump that is steadily enlarging, unusually firm and fixed, repeatedly scabs or bleeds, changes colour, or does not settle.

Ask: Does this feel like a cyst, inflamed nodule, or another type of growth? Does it need imaging, a sample, removal, or observation? Which changes should prompt an earlier review? If inflammation is suspected, what treatment is appropriate for facial skin?
