Lump Under the Skin on the Hip: What to Know

A lump under the skin on the hip needs attention to its texture, movement, skin changes, and how it develops over time. Many lumps are caused by non-serious changes such as a cyst, fatty tissue, an inflamed follicle, or friction from clothing. The hip is also exposed to pressure while sitting or sleeping, which can make a tender area more noticeable.

A soft lump that moves slightly beneath normal-looking skin can fit with a benign fatty growth or cyst, but appearance alone cannot identify it. A painful, warm, red swelling may be a boil or another inflamed process; see [Boils](/conditions/boils/) for related information. A firm spot that remains, grows, bleeds, crusts, or changes its surface should be assessed rather than labelled at home. [Skin Lumps](/symptoms/skin-lumps/) explains the broader symptom pattern. A skin cancer such as [Basal Cell Carcinoma](/conditions/basal-cell-carcinoma/) can sometimes appear as a changing skin growth, although a hip lump has many other possible explanations.

Note when you first noticed the lump, whether it moves, and whether pressure from a waistband or sitting changes the discomfort. Take an occasional photo beside a familiar object to compare surface changes, and avoid squeezing, piercing, or repeatedly pressing it. Arrange a routine clinical examination if it persists, enlarges, returns, or interferes with movement. Treatment depends on the finding; selected inflamed or raised lesions may be considered for [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/), but only after a clinician decides that approach is suitable.

Seek prompt medical care for a lump that becomes rapidly larger, very painful, hot, or increasingly red, or if pus, fever, or spreading redness develops. Arrange an examination soon if it is hard and fixed, repeatedly bleeds, forms a persistent crust, or does not settle. Seek urgent help if severe pain is accompanied by marked swelling, feeling faint, or difficulty walking.

Ask what the lump feels like on examination, whether its depth or position matters, and whether observation, imaging, drainage, or removal is appropriate. Mention recent friction, injury, injections, skin infection, or a change in size, colour, warmth, or tenderness.
