3. Causes The most common cause of acute paronychia is direct or indirect trauma to the cuticle or nail fold. Such trauma may be relatively minor, resulting from ordinary events, such as dishwashing, an injury from a splinter or thorn, onychophagia (nail biting), biting or picking at a hangnail, finger sucking, an ingrown nail, manicure procedures (trimming or pushing back the cuticles), artificial nail application, or other nail manipulation.3–5 Such trauma enables bacterial inoculation of the nail and subsequent infection. The most common causative pathogen is Staphylococcus aureus, although Streptococcus pyogenes, Pseudomonas pyocyanea, and Proteus vulgaris can also cause paronychia.3,6,7 In patients with exposure to oral flora, other anaerobic gram-negative bacteria may also be involved. Acute paronychia can also develop as a complication of chronic paronychia.8 Rarely, acute paronychia occurs as a manifestation of other disorders affecting the digits, such as pemphigus vulgaris.9
psychiatry Don’t try to puncture or cut into an abscess yourself. Doing that can lead to a more serious infection or other complications. The doctor may need to drain the abscess and possibly prescribe antibiotic medications to treat the infection. Once an abscess is treated, the finger or toe almost always heals very quickly.
Causes of paronychia Arthritis Infectious flexor tenosynovitis: This infection involves the tendon sheaths responsible for flexing or closing the hand. This is also a type of deep space infection.
Avoid contact with eyes; may irritate mucous membranes; resistance may result with prolonged use
Chronic paronychia can occur on your fingers or toes, and it comes on slowly. It lasts for several weeks and often comes back. It’s typically caused by more than one infecting agent, often Candida yeast and bacteria. It’s more common in people who’re constantly working in water. Chronically wet skin and excessive soaking disrupts the natural barrier of the cuticle. This allows yeast and bacteria to grow and get underneath the skin to create an infection.
Your doctor may send a sample of pus from your infection to a lab if treatment doesn’t seem to be helping. This will determine the exact infecting agent and will allow your doctor to prescribe the best treatment.

Diagnosis of chronic paronychia is based on physical examination of the nail folds and a history of continuous immersion of hands in water10; contact with soap, detergents, or other chemicals; or systemic drug use (retinoids, antiretroviral agents, anti-EGFR antibodies). Clinical manifestations are similar to those of acute paronychia: erythema, tenderness, and swelling, with retraction of the proximal nail fold and absence of the adjacent cuticle. Pus may form below the nail fold.8 One or several fingernails are usually affected, typically the thumb and second or third fingers of the dominant hand.13 The nail plate becomes thickened and discolored, with pronounced transverse ridges such as Beau’s lines (resulting from inflammation of the nail matrix), and nail loss8,10,13 (Figure 4). Chronic paronychia generally has been present for at least six weeks at the time of diagnosis.10,12 The condition usually has a prolonged course with recurrent, self-limited episodes of acute exacerbation.13

Some doctors will even suggest an acetic acid soak, using one part warm water and one part vinegar. If there is pus or an abscess, the infection may need to be incised and drained. In some cases, a portion of the nail may need to be removed.

All of my childhood paronychia were managed by my (non-medical) Mum, using hot water and encouragement to stop biting my nails (more on that later). But these patients do come to the Emergency Department, or minor injuries unit, so we should probably have some idea what to do with them.

Prosector’s Paronychia Common finger infections include paronychia, felon, and herpetic whitlow. A paronychia is an acute or chronic soft tissue infection around the nail body. Acute infections are typically bacterial in origin and usually occur after minor trauma. Chronic paronychia infections have a multifactorial etiology, often related to repeated exposure to moist environments and/or skin irritants, and may be accompanied by secondary fungal infection. The diagnosis of paronychia is based on clinical signs of inflammation. A bacterial culture or fungal stain can confirm the causative pathogen. Treatment of acute paronychia usually involves antibiotics, while chronic paronychia is treated with topical steroids and antifungal therapy. Complications include nail dystrophy or felon.
Hangnails are common, especially if your hands are dry because of the weather or from frequent exposure to water. Most hangnails will heal on their own without any signs of infection.

Cause Chronic paronychia responds slowly to treatment. Resolution usually takes several weeks or months, but the slow improvement rate should not discourage physicians and patients. In mild to moderate cases, nine weeks of drug treatment usually is effective. In recalcitrant cases, en bloc excision of the proximal nail fold with nail avulsion may result in significant cure rates. Successful treatment outcomes also depend on preventive measures taken by the patient (e.g., having a water barrier in the nail fold). If the patient is not treated, sporadic, self-limiting, painful episodes of acute inflammation should be expected as the result of continuous penetration of various pathogens.
If the nerves have infarcted, anesthesia may not be required for surgical intervention.8 In this case, the flat portion of a no. 11 scalpel should be gently placed on top of the nail with the point of the blade directed toward the center of the abscess. 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.
