Hard lump on hand under the skin

A bump near the wrist or a finger joint may be linked to a fluid-filled cyst or joint-related tissue. A thickened area in the palm can affect a tendon or the tissue beneath the skin. A recent knock can leave a firm healing area. Redness, heat, throbbing tenderness, or drainage points more toward inflammation or a boil. A surface lump that crusts, bleeds, or fails to heal needs a clinician’s assessment, including consideration of basal cell carcinoma.

Notice whether the lump changes when you flex the fingers, whether the skin moves over it, and whether grip, sensation, or strength has altered. Do not use these observations as a diagnosis; they simply make the clinical visit more useful.

Rest the hand from activities that repeatedly press on the area, but keep gentle movement unless movement causes marked pain. Do not hit the lump, puncture it, or attempt to squeeze it flat. Arrange an appointment if it persists, enlarges, returns, or interferes with work or daily tasks. Depending on the cause, a clinician may recommend monitoring, imaging, a procedure, or selected injection treatment.

Seek prompt care for spreading redness, warmth, pus, fever, rapidly worsening pain, or swelling after an injury. Urgent assessment is appropriate for a pale or blue finger, loss of sensation, new weakness, or inability to move it normally. Have a changing, fixed, ulcerated, or bleeding lump examined promptly even when it is not painful.

Ask whether the lump is connected to a joint, tendon, or skin; whether hand function is being affected; and whether imaging would clarify its origin. Ask whether observation is reasonable, which symptoms require faster review, and what treatment could protect movement.
