Cellulitis is a bacterial infection of the superficial and deep layers of the skin. In the finger tip, this is known as a felon.
Symptoms of a felon
Symptoms of a Felon or finger tip infection include a throbbing pain at the end of the finger. Felon's most common occur in the thumb or index finger. There may be swelling, inflammation and redness over the end of the finger.
Causes of a finger felon
Felon's sometimes occur after a minor injury to the finger tip, such as a splinter or small puncture wound. Fingertip blood glucose testing has been implicated as a cause of finger tip infections. They may also happen with no clear cause.
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 anti-biotic 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.
