Doctor's Notes on Finger Infection

A finger infection is an infection of the skin, soft tissue, or bone of the finger. The cause of the infection is typically a virus or bacteria, and a number of different organisms can cause a finger infection. Examples of medical conditions characterized by finger infection include herpetic whitlow, paronychia, felon, infectious flexor tenosynovitis, cellulitis, and deep space infection. Paronychia is a special type of infection that involves the nail.

Symptoms of finger infection can include pain and redness. Other associated symptoms can include swelling, the development of an abscess with drainage of pus, difficulty moving the finger, changes in the nails, and joint pain. The specific symptoms depend on the specific organism that is present along with the type of infection.
