What causes elbow lump?

Elbow lump is often caused by traumatic injury, such as a sharp blow to the elbow. In these cases, the elbow lump may be related to swelling of the elbow. In other cases, a benign growth or tumor might be responsible for the lump. If you have recently injured your elbow, the lump may be due to healing of a fractured bone in the elbow.

Common causes of elbow lump

Elbow lump may be caused by a variety of common conditions and events including:

  • Arthritis
  • Bursitis (inflammation of a bursa sac that cushions a joint)
  • Elbow or arm injury
  • Gout (type of arthritis caused by a buildup of uric acid in the joints)
  • Healing process of a broken bone
  • Overuse injury
  • Tendinitis (inflammation of a tendon)

Elbow lump can also be caused by some uncommon conditions including:

  • Abscess
  • Benign tumor
  • Cellulitis (infection of the skin and tissues beneath the skin)

Questions for diagnosing the cause of elbow lump

To diagnose your condition, your doctor or licensed health care practitioner will ask you several questions related to your elbow lump including:
