Cellulitis is a bacterial infection of the superficial and deep layers of the skin. In the fingertip, this is known as a felon. It is often caused by a small injury to the end of the finger which can make it painful and swell up. Read more about this infection and how to treat it.
Symptoms of a felon
Symptoms of a Felon or fingertip infection include a throbbing pain at the end of the finger. Felons most commonly 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
Felons sometimes occur after a minor injury to the fingertip, such as a splinter or small puncture wound. Fingertip blood glucose testing has been implicated as a cause of fingertip 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 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 anesthetic injection.
