acute paronychia management patient guidance warm soaks drainage oral antibiotics MSD Manual

The most likely diagnosis is acute paronychia: an early bacterial infection of the skin beside the nail after a small cut while trimming the nail. If redness is spreading beyond the nail fold, it may be developing into local cellulitis. Acute paronychia commonly follows trauma that breaks the cuticle or nail-fold barrier.

What to do now

  1. Warm water soaks: Soak the finger in warm water for 10 to 15 minutes, 3 to 4 times daily. Dry it well afterward.
  2. Keep it clean and protected: Wash gently with soap and water. Do not cut, squeeze, puncture, or try to drain it yourself. Avoid further nail trimming, biting, or picking.
  3. Elevation and pain relief: Keep the hand elevated when possible. Paracetamol/acetaminophen or ibuprofen can be used for pain if normally safe for that person.
  4. Topical treatment: If there is only mild redness/swelling and no pus or spreading skin infection, a clinician may recommend a topical antibiotic. Seek local medical or pharmacy advice because availability varies by country.
  5. Tetanus: Check whether tetanus vaccination is up to date, particularly if the cut was contaminated or the vaccine history is uncertain.

Get examined within 24 hours

Because swelling and redness appeared after 3 days, an in-person clinician should look for a small abscess. A visible yellow-white pus pocket, soft/fluctuant swelling, or throbbing pain can require sterile drainage. Do not attempt this at home. When abscess drainage is adequate, oral antibiotics are often unnecessary; antibiotics are more likely to be needed if there is spreading cellulitis, severe infection, diabetes, immune suppression, or systemic symptoms. The AAFP review and MSD Manual guidance support warm soaks for mild cases and drainage when an abscess is present.

Seek urgent care today if any of these occur

  • Rapidly spreading redness or swelling, red streaks up the hand/arm
  • Fever, chills, feeling unwell
  • Pus collection, severe throbbing pain, numbness, or inability to bend/straighten the finger
  • Swelling/redness involving much of the finger or hand
  • Diabetes, poor circulation, immune suppression, or use of chemotherapy/steroids
  • No improvement after 24 to 48 hours of home care
Remove any ring from that hand now if swelling is increasing.

Pus is there but mild

acute paronychia pus abscess do not drain at home urgent evaluation guidance

Visible pus means there is likely a small paronychia abscess, even if it is mild.
Please arrange an in-person medical visit today or within 24 hours. A clinician may need to release the pus using a sterile technique. Do not puncture it with a needle, blade, pin, or squeeze forcefully at home. Incomplete drainage can let infection spread around or beneath the nail.
Until seen:
  • Soak in warm water for 10 to 15 minutes, 3 to 4 times today.
  • Dry carefully and cover loosely with clean gauze.
  • Keep the finger elevated. Remove any rings from that hand.
  • Use paracetamol/acetaminophen or ibuprofen for discomfort if safe for you.
  • Do not trim the nail/cuticle further and do not use irritants such as strong antiseptics inside the wound.
Oral antibiotics are not automatically required after proper drainage, but a clinician may prescribe them if redness is spreading beyond the nail area, there is significant cellulitis, diabetes, reduced immunity, fever, or severe pain. Antibiotic selection needs local resistance information and allergy/medical-history review.
Go to urgent care today if redness is spreading, pain/swelling worsens, movement is painful or limited, you see red streaks, have fever/chills, or if you have diabetes or a weakened immune system. The AAFP paronychia guidance states that a confirmed abscess requires drainage.
