Components of the nail complex include the nail bed (matrix), the nail plate and the perionychium. The nail bed lies beneath the nail plate and contains the blood vessels and nerves. Within the nail bed is the germinal matrix, which is responsible for the production of most of the nail volume, and the sterile matrix. This matrix is the “root” of the nail, and its distal portion is visible on some nails as the half-moon–shaped structure called the lunula.1 The nail plate is hard and translucent, and is composed of dead keratin.2 The plate is surrounded by the perionychium, which consists of proximal and lateral nail folds, and the hyponychium, the area beneath the free edge of the nail1 (Figure 1).

The blade should be guided slowly and gently between the nail and the eponychial (cuticle) fold so that the tip of the blade reaches the center of the most raised portion of the abscess. Without further advancement, the scalpel should be rotated 90 degrees, with the sharp side toward the nail, gently lifting the eponychium from its attachment to the nail. At this point, pus should slowly extrude from the abscessed cavity. Because the skin is not cut, no bleeding should occur. Drains are not necessary. Warm-water soaks four times a day for 15 minutes should be performed to keep the wound open. Between soakings, an adhesive bandage can protect the nail area. Antibiotic therapy is usually not necessary.9 Recurrent acute paronychia may lead to the development of chronic paronychia. Here are some things that can lessen your chances of developing paronychia: Antibiotics (topical) What is the Evidence? DIFFERENTIAL DIAGNOSIS Chronic paronychia is a little different. It is a kind of dermatitis-type reaction, usually representing damage to the protective barrier of the nail or its tissues, often due to frequent hand washing and/or exposure to harsh chemicals or cold and wet (for this reason, chronic paronychia are more often seen in people who handwash a lot – such as healthcare workers, bar tenders and food processors – and in swimmers, fishermen etc.).

Soak the infected nail in warm water for 20 minutes a few times a day. The infection will probably heal on its own in a few days. Acute paronychia is typically diagnosed based on a review of the clinical symptoms. If there is a pus discharge, your doctor may perform a bacterial culture for a definitive diagnosis. (In all but the most severe cases, this may not be considered necessary since the bacteria will usually be either a Staphylococcus or Streptococcus type, both of which are treated similarly.)
