Hard Lump Under Skin on Palm of Hand: What to Know

A thickened or tethered area in the palm may catch during gripping or make a finger harder to straighten. A tender bump after friction or a puncture may be inflamed. A lump that is in the skin can differ from one that moves with a tendon or lies deeper. [Skin Lumps](/symptoms/skin-lumps/) offers general terminology. A surface lesion that persists, crusts, or bleeds should be examined; [Basal Cell Carcinoma](/conditions/basal-cell-carcinoma/) is one example of a condition clinicians may consider, but a palm lump does not identify its cause.

Do not cut, needle, or forcefully massage the lump. Reduce activities that create direct pressure, keep any broken skin clean, and note whether grip, finger extension, sensation, or strength changes. Arrange a clinical assessment if the lump lasts, grows, or interferes with daily tasks. If a clinician confirms an inflammatory skin nodule, they may discuss a Steroid Injection Into The Skin; deeper hand problems may require a different specialist.

Seek urgent care for sudden loss of movement or sensation, a pale or blue finger, severe pain after an injury, rapidly spreading redness, pus, or fever. Book a timely review for a growing, fixed, bleeding, or persistently painful lump, or one that causes locking or reduced grip.

Ask whether the lump appears to be in the skin, tendon, or deeper tissue; whether an ultrasound or other assessment is useful; and which exercises or pressure should be avoided. Ask when reduced movement needs faster review.
