Subungual Hematoma (Bleeding Under Nail) (cont.)


  • After the subungual hematoma has been drained, follow-up is usually not necessary.
  • Antibiotics are not routinely necessary after a subungual hematoma is drained.
  • If the nail was removed and a cut in your nail bed was stitched closed, you should see your doctor in 48-72 hours for re-examination.
    • Usually, the type of sutures (stitches) placed will dissolve, so removal is not needed.
    • If non-dissolvable sutures (nylon) are placed in a nail bed laceration, they need to be removed in about seven days in the emergency department or by your doctor.
    • Close monitoring is still recommended.

Subungual Hematoma Prevention

Use common sense and practice other safety-minded actions to prevent getting your fingers slammed in doors or dropping heavy objects on your toes.

  • Steel-toed shoes are important safety equipment to wear on certain high-risk jobs such as construction.
  • Watch children's hands as you open and close car doors.
  • Give your full attention to the task at hand. Finger injuries often happen when the person using the tool is distracted.
  • Don't lift something you cannot handle alone. Find people to help you carry heavy objects to avoid dropping them on your toes.
