The location can offer a clue: a bump directly beside a finger joint is different from a soft lump in the middle of the palm. Nevertheless, location alone is not enough to confirm a diagnosis.
If the lump is accompanied by persistent stiffness, joint pain, or reduced movement, a medical examination can help identify whether arthritis or another joint problem is involved.
Treatment depends on the underlying cause and may focus on relieving pain, maintaining movement, or treating the lump itself.
- Could It Be Related to an Injury?
Not all hand lumps develop spontaneously. Sometimes, swelling appears after a fall, a direct blow, repetitive strain, or an injury involving a tendon or joint.
A bruise or localized collection of blood beneath the skin can create a raised area. Inflammation following an injury can also cause temporary swelling.
However, a lump after an accident should not automatically be dismissed as a bruise. A fracture, tendon injury, or infection following a puncture wound can sometimes cause swelling and significant pain.
