With a good understanding of the cause, only then can effective treatment be provided.

Common Causes of Hand Swelling & Lumps

Injury or Trauma

  • Bruises or Hematomas: Caused by direct impact or injury, leading to bleeding under the skin, which can result in swelling and lumps.
  • Sprains or Strains: Damage to ligaments or muscles can cause swelling.

Infections

  • Abscesses: Localized infections can lead to the formation of pus-filled lumps.

  • Tendinitis or Bursitis: Inflammation of tendons or bursae can lead to swelling and lumps near the affected area.
