Mild acute paronychia without an abscess
Warm soaks, protection from further injury and, when appropriate, a prescription topical antibiotic may be sufficient. A topical anti-inflammatory medicine may be added selectively.

Painful nail fold · Bacterial infection · Dehradun
Red, swollen or pus-filled skin beside a nail? It may be paronychia.
Acute paronychia · bacterial infection · nail-fold abscess · chronic inflammation
Paronychia means inflammation of the skin around a nail. Acute paronychia is commonly bacterial, sometimes forming an abscess that needs drainage. By contrast, chronic paronychia is usually an irritant-driven inflammatory problem rather than a persistent bacterial or fungal infection. Treatment depends on which is present.
✓ Acute infection can follow a tiny skin break
✓ An abscess may require drainage
✓ Chronic disease needs nail-fold protection
Recognising the problem
Signs of acute and chronic paronychia
Acute: tender red fold
Pain, swelling and redness usually appear over hours to days, often beside one nail.
Acute: pus or abscess
A yellow-white fluid pocket may form; pressure and throbbing can increase.
Chronic: loss of cuticle
Swelling and tenderness recur for more than six weeks, sometimes involving several nails.
Chronic: changing nail surface
Ridges, irregular growth, discoloration or persistent nail-fold inflammation can develop.
Seek urgent medical care: Rapidly spreading redness, severe throbbing pain, fever, red streaks, numbness or trouble moving the finger; seek a lower threshold for care with diabetes, poor circulation or immunosuppression. Do not puncture an abscess at home.
Causes and triggers
Why does nail-fold inflammation occur?
- Acute bacterial paronychia often follows biting nails, hangnail pulling, picking cuticles, manicure trauma or another break in the protective skin barrier.
- Staphylococcus aureus and streptococci are common bacteria; nail-biting or thumb-sucking may introduce mouth organisms.
- Chronic paronychia is often linked to wet work, detergents, hand eczema and repeated irritation that damages the cuticle barrier.
- An ingrown toenail can also cause inflammation and infection at the nail fold.
- Green nail discoloration may suggest Pseudomonas colonisation/infection under a lifted nail (green nail syndrome), a related but distinct problem.
Common misconception: Persistent or recurrent chronic paronychia is not automatically Candida infection. Repeated antifungals often miss the main irritant/inflammatory cause.
Diagnosis
How the type of paronychia is identified
1. Assess timing and number of nails
A rapid painful change affecting one digit suggests acute disease; repeated symptoms involving several digits raise the possibility of chronic irritant disease.
2. Check for an abscess
Examination looks for a fluctuant collection of pus versus inflammation alone. Ultrasound is occasionally useful if uncertainty remains.
3. Review exposures and risk factors
Nail biting, manicures, detergents, eczema, diabetes, immunosuppression, injury and ingrown nails can alter the approach.
4. Look for important mimics
Herpetic whitlow, felon, psoriasis and an unusual persistent nail-fold tumour may resemble paronychia. Herpetic whitlow must not be incised.
Routine bacterial swabs, blood tests and X-rays are not needed for uncomplicated cases. Cultures or imaging may be selected for severe, recurrent, unusual or non-healing presentations.
Treatment
Treatment is based on infection and abscess status
Acute paronychia with a pus collection
A well-formed abscess generally needs clinician-performed drainage using a suitable technique and local anaesthesia if necessary. Do not squeeze or cut it yourself.
Oral antibiotics only when justified
Tablet antibiotics are reserved for selected circumstances such as spreading cellulitis, systemic symptoms, immunocompromise or other significant risk factors. They are not automatically needed after adequate drainage.
Chronic paronychia: restore the barrier
Chronic paronychia is usually an inflammatory disorder of the nail-fold barrier, often maintained by frequent wet work, detergents, irritants and repeated cuticle trauma. Treatment starts with reducing these exposures: avoid picking or cutting the cuticle, keep hands dry where practical, use cotton-lined protective gloves for wet work and moisturise after washing. A dermatologist may prescribe a topical corticosteroid for the inflamed nail folds; topical tacrolimus may be considered in selected persistent cases. Neither is a universal self-treatment, and prolonged potent steroid use can cause local adverse effects. Candida may colonise affected folds, but routine repeated antifungal or antibiotic courses are not the main treatment unless a relevant infection is established. As inflammation settles, the cuticle seal can gradually reform; improvement often takes weeks to months. Persistent or unusual inflammation of one nail should be reassessed to exclude other causes.
Treat underlying contributors
Control hand eczema, assess any ingrown nail and manage a proven secondary infection when appropriate. Refractory single-nail disease may need further work-up.
What if the pain is due to herpetic whitlow?
Grouped clear blisters and severe finger pain may suggest herpes infection rather than a bacterial abscess. Herpetic whitlow should not be incised or drained like bacterial paronychia.
Prevention & follow-up
Prevent recurrence and protect the cuticle
- Avoid biting nails, chewing cuticles and tearing away hangnails.
- Do not cut or push the cuticle aggressively during manicures.
- Use gloves when handling detergents or doing prolonged wet work; dry hands gently afterward.
- Follow prescribed wound care if an abscess was drained and return for increasing pain, pus or spreading redness.
- Understand that chronic paronychia may take several weeks or months to settle fully.

Patient questions
Frequently asked questions
Is all paronychia bacterial?
No. Acute paronychia is commonly bacterial, but chronic paronychia is usually caused by repeated irritation and inflammation of the nail folds.
Will antibiotics cure a nail-fold abscess?
An established abscess often requires drainage; antibiotics alone may not be sufficient.
Do I need oral antibiotics after drainage?
Not routinely after adequate drainage of an uncomplicated abscess. Tablets are selected when cellulitis, systemic illness or relevant risk factors are present.
Is Candida the cause of chronic paronychia?
Candida can sometimes be present, but chronic paronychia is predominantly an irritant-inflammatory condition. Routine repeated antifungals are often not helpful.
Can I puncture the pus myself?
No. Self-puncturing risks injury, further infection and delayed recognition of conditions such as herpetic whitlow.
Does a green nail mean paronychia?
Not necessarily. Green nail syndrome often involves Pseudomonas affecting a separated nail and is assessed differently.
