Treatment for cellulitis (finger felon)

  • If you suspect a felon or cellulitis of the finger then seek medical attention or visit a doctor as soon as possible.
  • If an infection is diagnosed then the Doctor will prescribe antibiotic medication to clear the infection.
  • In most cases, this is all the treatment which is required and the infection will clear by the end of the course.
  • In severe cases, where the blood flow may be compromised, decompression may be required.
  • This involves a small incision in the fingertip so that fluid can be drained and so pressure released and is done under a local anaesthetic injection.
